The central quadrangle of the British Museum in London was redeveloped to a design by Foster and Partners, from a 1970s design by Colin St John Wilson,[1] to become the Queen Elizabeth II Great Court, commonly referred to simply as the Great Court, during the late 1990s. It was opened by Queen Elizabeth II in 2000. The court has a tessellated glass roof designed by Buro Happold[2] covering the entire court and surrounds the original circular British Museum Reading Room in the centre, now a museum.
