While Galleria Continua occupies spaces all over the world, including Beijing, Havana, São Paulo, and Rome, its beating heart is in a former 1930s cinema in San Gimignano, the Tuscan hill town encircled with 13th-century walls that boasts a number of extraordinary medieval towers. Here, the gallery hosts a major artist every summer, this year being no exception, and its intriguing interior and garden—with a spectacular view over the Tuscan landscape—is filled with the work of Ai Weiwei.
