The museum opened in 2002 in Bristol's historic old railway station, designed by Isambard Kingdom Brunel, following renovation and conversion costing £8 million. It was completed in 1840 and includes the passenger shed and the adjoining former engine and carriage shed. It is over with timber and iron roof spans of, this Grade I listed building has been nominated as part of a World Heritage Site. The museum had a flourishing publications department, producing books on aspects of colonial life such as the history of the Northern Rhodesia Police, and a register of titles of the regiments of the Honourable East India Company and East Indian Armies. The museum also held the collection of artefacts of the Commonwealth Institute; extensive photograph stills, paper, film and oral history archives, and a costume collection. These are now in the care of Bristol Museums, Galleries & Archives. The museum was also the home of the New World Tapestry. Unlike many national museums in Britain, the BECM was not publicly funded, but owned and operated by a charitable trust; consequently an admission charge was in place.
On 23 November 2007 the museum announced it would be moving its core operations to London in 2008. The museum closed to the public in the autumn of 2008 and for school visits at the end of March 2009. On 16 March 2011, the Museums Association announced that the Director of the museum, Gareth Griffiths, had been dismissed pending a police investigation into the unauthorised disposal of museum objects. On 28 March 2012, the museum announced that the planned move to London had been cancelled and that it would instead give its collection to the City of Bristol to display at the Bristol City Museum and Art Gallery at a future date. The Old Station which had previously housed the museum was also given to the city, and may be used for future Network Rail services to London. The unauthorised sale of hundreds of items from the museum's collection was the subject of a BBC OneInside Out programme on 10 December 2012. In a letter dated 22 May 2013, the museum wrote to one of the lenders of items, "Following a further extensive search for the items, I can now confirm that, unfortunately, we have only been able to locate one of the ten ... It is a matter of great regret that the Museum cannot locate the remaining items and I apologise on behalf of the Museum's trustees for this. I also confirm that the Museum has now completed the transfer of the artefacts it held to the British Empire & Commonwealth Trust and the Museum has now moved out of its premises and it is proposed that the company which operates the Museum will be wound down in the near future, with an intention to enter a Members Voluntary Liquidation in July 2013." On 24 October 2013, The British Empire and Commonwealth Museum and The Empire Museum Ltd were placed into "members' voluntary liquidation"; two employees of PricewaterhouseCoopers, Bristol, were appointed joint liquidators.
Missing items
The following is a partial list.
Thomas Buttersworth's painting of the East India Company'sDunira, loaned by Lord Caldecote, was later discovered to have been sold at auction in 2008 without the owner's consent.
After the closure of the museum the collections were given to Bristol City Council to care for, with the objects under the care of Bristol Museum and Art Gallery and the archive collections under the care of Bristol Archives. Since 2014 Bristol Archives have worked to catalogue some of the photographic and film collections, digitise them and make them available for public use.
