The Ascension, Lavender Hill, was principally conceived by Fr John Bourdieu Wilkinson SSC. As a young man Wilkinson had often sat on Clapham Common and gazed down upon the blue fields of lavender which made up the historic Lavender Hill. He often dreamt that if he ever was called to become a priest, it would be upon the Lavender Hill where he would build a church for the faith to be proclaimed. Eventually his priestly calling began to materialize and he was ordained. Now a priest, Wilkinson was sent to St Barnabas, Pimlico where the effects of the "ritual riots" – a series of protests against high church practices in use there – were being felt. It was these riots that influenced Wilkinson, supported by a number of wealthy ladies from the Pimlico congregation, to conceive the idea of an Anglo-Catholic sanctuary away from the troubles of Central London. Amongst those who financially contributed to the building of the new church were Lady Anne Antrobus, wife of Sir Edmund Antrobus, her sister-in-law through marriage, The Hon Jane Duff-Gordon, and a young dowager, Amelia, Lady Boston. A sizeable benefaction made by the ladies was used to purchase the grounds of Pountney House which ran from what is now Acanthus Road to the end of Crown Terrace, and north of the church to Elsley Road. Only about a third of this land now remains in church hands. It was not until 1872, that Father Wilkinson, Lady Antrobus and the Hon. Mrs. Jane Duff-Gordon moved to Lavender Hill and the plot of land on which the church stands was purchased, thanks to the generosity of Lady Boston.
Construction
The people of the Shaftesbury Estate, many of them railway workers who had moved from the East End to work at nearby Clapham Junction made it clear that they wanted the Ascension to resemble the churches that many of them had left behind in east London. With that in mind, a significant Anglo-Catholic architect, James Brooks, was commissioned to design what was to be one of his finest churches. The foundation stone was laid on 1 June 1874, by John Patrick Boyle, Earl of Glasgow; according to Henry Simmonds in All About Battersea it was situated "under the altar" of the temporary church. It was not long before Brooks soon discovered that he was using too much of the available funds for the foundations of the new church. His clients quickly became alarmed by this unforeseen expense, and he was subsequently dismissed as architect. His replacements, J. T. Micklewaite and Somers Clark, completed the church almost entirely to Brooks’ original specification. The overspend, however, meant that some of Brooks more elaborate design features, such as the carving of the stone capitals in the nave, the projected tower with steeple, above what is now the south porch, a belfry and an elaborately carved stone reredos could not be completed. Like Brooks' East End churches, the Ascension is a bold, simple design, built of brick. A continuous roofline runs the full length of the building. The nave is lit by lancet windows in the clerestory; there are no aisle windows. There is a narrow ambulatory around the chancel. The arcades are supported by short cylindrical columns, with square capitals, plain in the nave and carved with foliage in the chancel. The brickwork above the arcades is left bare. Francis Bumpus noted the French Cistercian influence on the Ascension, and on his Holy Innocents in Hammersmith, saying that both buildings were "conceived in a bold and vigorous Early Pointed style, recalling such Burgundian examples as Auxerre and Pontigny" and admirably adapted to contemporary requirements. The new church was consecrated for worship by the Bishop of Bishop of Rochester, Anthony Thorold, within whose diocese the parish then was, on 30 June 1883.
Fire
Just before 7pm on Friday 13 April 1979, which happened to be Good Friday, a fierce fire broke out, quickly spreading along the church roof, and threatened to destroy the building in its entirety. The London Fire Brigade sent fire fighters from some six stations, some of whom worked throughout the night to ensure that this historic landmark was saved. The then Parish Priest Fr John CuthbertCMP, praised the work of the fire service, recognizing that without their assistance the damage sustained to the building would have been far worse.
