Originally home to the island’s customs office, postal service, and district courts, this four-story architectural marvel was built to keep pace with the increasing population and wealth accumulating from Key West’s lucrative trade routes and maritime industries. Today, “Old 91” has been faithfully restored and stands on the harbor as a national landmark, an award-winning museum and official headquarters of the Key West Art & Historical Society. Experience two floors of exhibitions that weave together two centuries of history, art, people, and events.
