An architectural feat, this magnificent site integrates 19th-century British military buildings, including a couple of explosives magazines, and transforms them into an exhibition gallery, a multipurpose theatre, an excellent restaurant and a bookstore, all open to the public. The architects Tod Williams and Billie Tsien eschewed bold statements for a subdued design that deferred to history and the natural shape of the land. The result is a horizontally oriented site that offers an uplifting contrast to the skyscrapers nearby. Experience it with a meal at AMMO .
