Old American Legation Museum

This cultural centre dating from 1821 is home to America's oldest foreign diplomatic mission, and is that country's only overseas National Historic Landmark. It's a mansion hosting a fascinating museum telling the story of international Tangier through a fine collection of paintings and artifacts. Highlights include a section dedicated to the novelist Paul Bowles (who wrote The Sheltering Sky here), and the correspondence of a hapless American diplomat who was gifted a lion by his Moroccan host.
