Chicago-based artist Theaster Gates launched Sanctum, a 24-day performance in Bristol, England that will have continuous programming 24 hours a day.

Gates set the performance in Temple Church, a 14th-century building that was bombed out during the Bristol Blitz in World War II. The temporary venue was constructed out of leftover building materials from all over the city: brick and doors from local homes, bricks from the demolished citadel in St. Paul’s, wood from the Prince Street bridge, and flooring from a former chocolate factory nearby.

Produced by the art organization Situations, the performance line up will not be published so visitors will not know what they will hear until they enter the space. Sanctum will be open through November 21.
