If the gallery was intended as a catalyst for regeneration in Margate then it’s hard to argue with its success. Since it was opened in 2011 by the Kent town’s most famous daughter, Tracey Emin, Turner Contemporary has had more than 3.5 million visits and shown work by more than 500 artists, from Turner, Rodin and Constable to Ai Weiwei, Barbara Walker and Grayson Perry. It has hosted more than 50 exhibitions, as well as the Turner prize, and put more than £70m into the local economy.
