Milton Curry was the first millionaire in Florida, and in 1905 he built his mansion in Key West. It's a three-story imposing structure full of antiques and memorabilia evoking opulence and Old Key West. There's an 1800's billairds table and other attic-ey items such as old luggage and antique dresses. It's now a Bed & Breakfast and museum, with self-guided tours available.
Curry Mansion is open for exploration every day from 10am to 5pm, with small admission fee. You can stay here, and at the adjacent building.
