Which of these British exhibition and music venues was permanently closed in 2014?

Earls Court Exhibition Centre was an internationally renowned exhibition, conference and events venue in London that originally opened in 1887 and was built in 1937 in its most recent art moderne style exterior. It was located in Earl's Court within the Royal Borough of Kensington and Chelsea and was the largest such venue within central London. The founder was John R. Whitley and the first exhibition included performances by Buffalo Bill Cody as part of the 'American Exhibition'. This was followed by 'Four National Exhibitions', the title of C. Lowe's 1892 book about Earls Court and its founder.

In 2013 plans to demolish Earl's Court were approved in order to make way for a new residential and retail estate on the site, which is expected to be completed in 2033. Demolition work began on the site in December 2014.

Earl's Court was widely known for serving as London's premier exhibition hall for many decades, hosting the Royal Tournament and Earl's Court Motor Show, Ideal Home Show, the Brit Awards (until 2010), Crufts Dog Show and a number of other notable events and concerts. It was also used as one of the venues for both the 1948 and 2012 Olympic Games. It was served by two London Underground stations: Earl's Court and West Brompton, opposite its entrances on Warwick Road and Old Brompton Road respectively.
