Looking like a faux Spanish castle from a medieval theme park, this odd gray edifice was built in 1883 by an eccentric millionaire who was obsessed with Spain's 12th-century Alhambra Palace, it's made from a mix of concrete and local coquina shells. Today, it's an odd-but-engaging museum. The Moorish-style atrium and rooms contain quirky antiques and archaeological pieces: highlights being a 2400-year-old mummy's foot and an Egyptian 'Sacred Cat Rug.'
