Make it a point to mail a postcard from this 1937 deco gem of a post office, the very first South Beach renovation project tackled by preservationists in the '70s. This Depression moderne building in the ‘stripped classic’ style was constructed under President Roosevelt’s reign and funded by the Works Progress Administration (WPA) initiative, which supported artists who were out of work during the Great Depression. On the exterior, note the bald eagle and the turret with iron railings, and inside, a large wall mural of Florida’s Seminole Wars.
