Birkenhead


Birkenhead is a town in the Metropolitan Borough of Wirral, Merseyside, England; historically, until 1974, in Cheshire. It is on the Wirral Peninsula, along the south bank of the River Mersey, opposite the city of Liverpool. At the 2011 census, it had a population of 88,818.
Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution. Birkenhead Park and Hamilton Square were laid out as well as the first street tramway in Britain. The Mersey Railway connected Birkenhead and Liverpool, with the world's first tunnel beneath a tidal estuary, and the shipbuilding firm Cammell Laird and a seaport were established.
In the second half of the 20th century, the town suffered a significant period of decline, with containerisation causing a reduction in port activity. The Wirral Waters development is planned to regenerate much of the dockland.

Toponymy

The name Birkenhead probably means "headland overgrown with birch", from the Old English bircen meaning birch tree, of which many once grew on the headland which jutted into the river at Woodside. The name is not derived from the Birket, a stream which enters the Mersey between Birkenhead and Seacombe. The Birket is a later name which was introduced by Ordnance Survey.

History

Medieval period

The earliest records state that the Mersey ferry began operating from Birkenhead in 1150, when Benedictine monks under the leadership of Hamon de Mascy built a priory there. The priory was visited in 1275 and 1277 by Edward I. In a royal charter of 13 April 1330, Edward III granted the priory further rights.

19th century

Distanced from the Industrial Revolution in Liverpool by the physical barrier of the River Mersey, Birkenhead retained its agricultural status until the advent of steam ferry services. In 1817 a steam ferry service started from Liverpool to Tranmere and in 1822 the paddle steamer, Royal Mail, began operation between Liverpool and Woodside.
Shipbuilding started in 1829. An iron works was initially established by William Laird in 1824 and was joined by his son John Laird in 1828. The business eventually became Cammell Laird. Notable naval vessels built at Birkenhead include HMS Achilles,,,,,,, the pioneer submarine, , and. Merchant vessels were also built such as and.
In 1833 an act was passed to introduce street paving, lighting and other improvements in the town. These included establishing a market and regulating the police force.
The Mersey Railway tunnel opened in 1886, providing direct railway access to Liverpool.

20th century

The Grange Road West drill hall was completed in 1900.
In September 1932 thousands of unemployed people protested in a series of demonstrations organised by the local branch of the National Unemployed Workers Movement. After three days of rioting, police were brought in from elsewhere to help quell the rioters.
In addition to the ferries and the railway, the Queensway road tunnel opened in 1934 and gave rapid access to Liverpool. This opened up the Wirral Peninsula for development, and prompted further growth of Birkenhead as an industrial centre. Bolstered by migration from rural Cheshire, southern
Ireland and Wales, the town's population had grown from 110 in 1801 to 110,912 one hundred years later and stood at 142,501 by 1951.
Birkenhead was struck by an F0/T1 tornado on 23 November 1981, as part of the record-breaking nationwide tornado outbreak on that day.

Governance

Formerly a township in Bidston Parish of the Wirral Hundred, Birkenhead was incorporated as a municipal borough in 1877, and became a county borough with the passing of the Local Government Act 1888. The borough included the parish of Birkenhead St. Mary and the townships of Bidston, Claughton with Grange, Oxton, Tranmere and part of Bebington, later known as Rock Ferry.
The townships of Landican, Prenton and Thingwall were added in 1928, followed by Noctorum, Upton and Woodchurch in 1933.
Prior to 1 April 1974, Birkenhead and the rest of the Wirral Peninsula were part of the county of Cheshire. The implementation of the Local Government Act 1972 caused Birkenhead to lose its county borough status. The town has since been administered as part of the Metropolitan Borough of Wirral, in the metropolitan county of Merseyside. The Birkenhead and Tranmere electoral ward had a population of 15,879 in 2011.
The current Member of Parliament for Birkenhead is Mick Whitley.

Geography

The Birkenhead Urban Area, as defined by the Office for National Statistics, includes Birkenhead, Wallasey, Bebington, Ellesmere Port and the contiguous built-up areas which link those towns. In the 2011 Census, the area so defined had a total population of 325,264, making it the 19th largest conurbation in England and Wales.

Economy

Shipbuilding

Shipbuilding and ship repair has featured prominently in the local economy since the 19th century. Cammell Laird entered receivership in 2001. The shipyard was sold and became 'Northwestern Shiprepairers & Shipbuilders', which grew into a successful business specialising in ship repair and conversion, including maintenance contracts for the Royal Fleet Auxiliary. In September 2007 NS&S acquired the rights to use the Cammell Laird name. The company was renamed 'Cammell Laird Shiprepairers & Shipbuilders' on 17 November 2008, seeing the famous name return to Birkenhead after a seven-year hiatus. In 2010, Cammell Laird secured a £50 million contract to construct the flight deck for, the first of two s. In 2015, Cammell Laird was selected as the preferred bidder to construct, a Royal Research Ship.

Commerce

Birkenhead Market was first established on what is now the site of Birkenhead Town Hall, between Chester Street and Hamilton Street, on 10 July 1835.
An increase in the town's population by 1841 led to the opening on 11 July 1845 of a much expanded market on a larger site nearby. This market hall was built by Fox, Henderson & Co, who later built The Crystal Palace. Michael Marks, of Marks & Spencer, opened one of his first seven 'Penny Bazaar' stalls here during the 1880s. On 31 January 2018, Marks & Spencer announced the closure of their store, in the town centre of Birkenhead, happening in April.
During the 1970s, the commercial centre of the town was redeveloped around the principal shopping area of Grange Road. Following two fires at the expanded Birkenhead Market in 1969 and 1974, it was moved to new premises adjoining the Grange Shopping Precinct development in 1977. Commercial expansion continued in the early 1990s when the Pyramids Shopping Centre was opened. The previous market site has been redeveloped with the construction of two office buildings, primarily to house Land Registry and Department for Work and Pensions offices.

Economic statistics

In February 2010, the town had an overall unemployment rate of 8.2% as against a national average of 4.4%.

Demography

In 2011, Birkenhead had a population of 88,818. The wider Urban Subdivision had a population of over 142,000. However, this latter figure includes areas such as Greasby and Frankby, which are separate from Birkenhead.

is acknowledged to be the first publicly funded park in Britain.
The park was the forerunner of the Parks Movement and its influence was far reaching both in Britain and abroad – most notably on Frederick Law Olmsted's design for Central Park.
Designed by Joseph Paxton in 1843 and officially opened in 1847, with great festivity. The park's Grand Entrance, modelled on the Temple of Illysus in Athens, and its 'Roman Boathouse' are notable features. There are sandstone lodges at the three entrances, each with a different style of architecture, Gothic, Norman and Italianate. There are also two lakes and an ornate 'Swiss Bridge'.
William Laird, a Scot, and his son John, were influential in the design of the town. Parts were laid out in a grid-iron pattern like Edinburgh New Town with similar architecture. The chief architect was James Gillespie Graham from Edinburgh. This grid pattern was centred around Hamilton Square which was started in 1826 and, apart from Trafalgar Square in London, contains the most Grade I listed buildings in one place in England. including Birkenhead Town Hall. A short distance from Hamilton Square are two other notable landmarks: the Queensway Tunnel Main Entrance and the Woodside Ferry Terminal. The film Chariots of Fire had scenes shot at Woodside. These scenes were as a representation of Dover in the 1920s.
Other notable landmarks include Bidston Windmill on a ridge behind the town, Flaybrick Watertower and Birkenhead Priory & St. Mary's Tower.

Transport

Trams

Birkenhead had the first street tramway in Britain. Opened on 29 August 1860 the first line ran from Woodside to Birkenhead Park. This early system was horse-drawn and was the brainchild of flamboyant American, George Francis Train.
A preserved tram was on display in the Woodside ferry terminal booking hall.
The system was later electrified and operated from 1901 as Birkenhead Corporation Tramways. Two replica trams, imported from Hong Kong, have been brought into service as part of a heritage tramway between Woodside and Wirral Transport Museum, and Birkenhead Corporation Tramways Car No.20 is preserved on this line.

Buses

Horse-drawn buses began operating in Birkenhead in 1848, to be replaced with motor vehicles after the First World War.
Present-day services are run by operators including Arriva and Stagecoach and coordinated by Merseytravel. Birkenhead bus station opened in 1996.
National Express provides long-distance coach services to other UK cities, with direct routes including London, Glasgow, Bangor and Newcastle.

Birkenhead Bus Station

Birkenhead Bus Station serves the town of Birkenhead. It is adjacent to The Grange Shopping Centre and Birkenhead Market.
It has a total of eleven stands and incorporates a travel centre. The main bus operators at the station include Arriva North West, Avon Buses and Stagecoach North West
Bus services using the bus station operate around the town of Birkenhead, throughout the Wirral, and to the nearby city of Liverpool via the Queensway Tunnel. The station also has frequent services to as far away as Chester.

Railways

Railways reached Birkenhead in 1840, when the Chester and Birkenhead Railway began services. Birkenhead Grange Lane railway station opened at the same time, becoming the town's first terminus. Birkenhead Dock railway station opened in 1866, as the eastern terminus of the Hoylake Railway. With the opening of the Woodside and Birkenhead Dock Street Tramway in 1873, this station probably became the world's first tram to train interchange. In 1886 Birkenhead and Liverpool were linked by an underground railway system, which today is part of the Merseyrail network.
The major underground station in Birkenhead is Hamilton Square, the nearest station to the ferry terminal. Hamilton Square station is linked to the "Liverpool Loop" of the Wirral Line, which includes James Street, Moorfields, Liverpool Lime Street and Liverpool Central stations, all of which are underground. Other stations located in Birkenhead include Birkenhead Central which is open but below ground level, Green Lane which is below ground level, Rock Ferry, Conway Park which is below ground level, Birkenhead Park, Birkenhead North and Bidston.
The Wirral Line from Birkenhead travels south to Chester and Ellesmere Port, north to New Brighton and westwards, across the Wirral Peninsula, to West Kirby. The Borderlands Line leaves Bidston station, in the north of Birkenhead and travels through the rural centre of Wirral, ultimately leaving England near Shotton and terminating in Wrexham, Wales.
From 1878, until its closure in 1967, Birkenhead Woodside railway station was the town's mainline railway terminus. Originally located close to Woodside Ferry Terminal, the site had been redeveloped as part of Cammell Lairds ship builders. Latterly the adjacent dry dock at Cammell Lairds was filled in and the whole area redeveloped to provide flats, a bus depot and offices for HM Land Registry and Child Support Agency.
The town has one operational railway depot, Birkenhead North TMD; one disused, Birkenhead Central TMD; and two demolished, Birkenhead Mollington Street TMD and a further depot adjacent to Birkenhead Park station. The remains of the Birkenhead Dock Branch are still extant in a cutting through the centre of the town, which was used primarily for freight services. Much of the peripheral railway infrastructure, around the docks, has been removed since the 1980s.

Roads

Junctions 1 and 3 of the M53 motorway allow access to the national motorway network. The A41 trunk road connects Woodside with Marble Arch in London. Two road tunnels, the Queensway road tunnel from Birkenhead, and the Kingsway road tunnel from Wallasey, run underneath the River Mersey and connect the town to Liverpool.

Maritime

Birkenhead's dock system is part of the Port of Liverpool, operated by the Mersey Docks and Harbour Company under the ownership of The Peel Group. The Twelve Quays ferry terminal allows a direct freight and passenger vehicle service to Dublin, Ireland and Belfast, Northern Ireland. Daily Belfast services are run by Stena Line, using their RoPax ferries and. The Mersey Ferry at Woodside operates a passenger service to Liverpool and chartered cruising.
During winter months, the Isle of Man Steam Packet Company operates a service from Birkenhead to Douglas using. Due to weather conditions, this service temporarily replaces the route that normally operates from the Liverpool landing stage using fast craft.

Education

Schools

Birkenhead has a number of maintained schools, including Birkenhead Park School and the only all-boys Catholic grammar school in the area St. Anselm's College.
Birkenhead also has two independently run schools. The oldest is Birkenhead School. It was exclusively a boys' school from its founding in 1860 until 2000, when its sixth form became co-educational. It became fully co-educational for pupils aged 3–18 in 2008. "Old Birkonians" include the lawyer F.E. Smith ; Andreas Whittam Smith ; Andrew Irvine, and Philip Toosey, hero at the Bridge on the River Kwai; and Tony Hall, Director-General of the BBC.
Birkenhead High School Academy, formerly Birkenhead Girls High School, is an all-ability state funded girls' Academy. It was founded in 1885 and caters for girls aged 3–19. Its sponsor was the Girls' Day School Trust, but is now publicly funded. Its alumnae include the actress Patricia Routledge. Birkenhead Girls High School decided to become a state-funded Academy school in 2009, increasing the availability of its education. Like the change to co-education at Birkenhead School, this decision was largely driven by falling pupil numbers; however to this date, it remains a single sex school.
Birkenhead Institute Grammar School existed from 1889 in Whetstone Lane, before being moved to Claughton in the 1970s. The school closed in 1994. The school's alumni include Wilfred Owen.

Colleges

Previously situated at Borough Road, Birkenhead's college has campuses at Europa Boulevard and Twelve Quays. The college was originally Birkenhead Technical College, and has been known as Wirral Metropolitan College since the 1980s. The college had a theatre on Borough Road named after one of its most famous former students, Glenda Jackson, the Oscar-winning actress and Member of Parliament, herself a Birkonian, born in 1936. The Borough Road campus and the Glenda Jackson Theatre were demolished in late 2005, to make way for flats, although Wirral Metropolitan College flourishes on other sites across Wirral. The theatre secretly housed an emergency command centre for the region in its basement, accessible via the college. Politicians and officials would have retreated to this secure bunker in the event of nuclear war to co-ordinate the recovery effort. By the 1990s, after the end of the Cold War, the bunker had been decommissioned and the surrounding complex of rooms was used by the college as a rehearsal space and recording studio.
Other colleges include the Birkenhead Sixth Form College, located in the Claughton area of Birkenhead, formerly the site of Corpus Christi Catholic High School.

Arts and leisure

Arts

The Laird School of Art was the first public school of art outside London and was given to the town by John Laird. It opened on 27 September 1871. The Williamson Art Gallery was opened in 1928 and houses a fine collection of paintings, porcelain and pottery.
In 1856, Birkenhead Library was opened as the country's first public library in an unincorporated borough.
The library was situated in Hamilton Street until 1909, when it moved to a new building in Market Street South, near Birkenhead Market. In the 1930s, this building was demolished to make way for the entrance to the Queensway Tunnel. The present library, Birkenhead Central Library, is situated on Borough Road and was opened by King George V in 1934.
Despite being in England, Birkenhead hosted Wales' National Eisteddfod in 1917 as well as an unofficial National Eisteddfod event in 1879. As in Liverpool, migrants from Wales, especially North Wales, contributed greatly to the growth of the town and its cultural development in the 19th century. The first local Birkenhead Eisteddfod, a precursor of the national events, took place in 1864. The 1917 National Eisteddfod was notable for the award of the chair to the poet Ellis Humphrey Evans, known as Hedd Wyn. The winner was announced, and the crowd waited for the winner to accept congratulations before the chairing ceremony, but no winner appeared. It was then announced that Hedd Wyn had been killed the previous month on the battlefield in Belgium, and the bardic chair was draped in black. These events were portrayed in the Academy Award nominated film Hedd Wyn, and were apparently intended as a protest against the war policies of Prime Minister David Lloyd George, who was present. There is a commemorative stone for the event in Birkenhead Park. The first meeting of the international Celtic Congress also took place at the Birkenhead Eisteddfod.
The Argyle Theatre was a major theatre and music hall which opened on 28 December 1868 and became notable for the calibre of artistes who appeared there. Later in its life, it was also used as a cinema. The theatre was destroyed by bombing in 1940.
The Theatre Royal, opened on 31 October 1864, was in Argyle Street and had a capacity of 1,850. This theatre was closed in 1919 and demolished in the 1930s. Another theatre, the Hippodrome, which was converted into a cinema in the 1930s, stood on the site of what became the Co-operative department store in Grange Road.
The Little Theatre was established in 1958 from a converted former Presbyterian church. The Pacific Road Arts Centre in Woodside opened in 1999, but in 2015 was converted to a “Business Hub”.

Leisure

As well as Birkenhead Park, other recreational open spaces in Birkenhead include Mersey Park and Victoria Park. Arrowe Park is a large area of parkland at the western edge of the town. In 1929, the 3rd World Scout Jamboree was held there.
The first two Boy Scout groups in the world are thought to have been founded as the 1st and 2nd Birkenhead groups at YMCA on the same night in 1908. The 2nd Birkenhead Scout Group is still operating and therefore is the longest running scout group in the world.

They returned to the Football League three seasons later, after a 2-1 play off final win against Boreham Wood F.C.. Cammell Laird 1907 F.C. is the town's semi-professional football club who play at Kirklands in Rock Ferry. They play in the North West Counties League Division One.
The Birkenhead Park Football Club was founded in 1871, the same year as the Rugby Football Union. The club originally played in the Lower Park but moved to their current home in the Upper Park in 1885. Birkenhead Park also has its own cricket club.

Birkenhead also has a Sister City Agreement with:
The major redevelopment project under consideration is Peel Holdings' "Wirral Waters". This would allow for £4.5 billion of investment in the regeneration of the dockland area. This equates with an investment of over £14,000 for each of the 320,000 residents of the Wirral. At the East Float and Vittoria Dock, the development would include several 50-storey skyscrapers, of new office space and for new residential flats. A retail and leisure quarter at the former Bidston Dock site would encompass another of space. The whole project would create more than 27,000 permanent new jobs, aside from the employment required for construction and other peripheral employment. The development would be expected to take up to thirty years.
