Looking like a ship, with jutting white slats and porthole windows, this handsome building across from the A-Ma temple is a great place to spend an interesting hour brushing up on seafaring history. A row of fountains out front soothes you almost as much as the calm, cool interior. Multimedia exhibits cover fishermen, merchants, and explorers from Portugal, South China, and Japan. Look for compasses, telescopes, and sections of ships. There's even a small aquarium gallery with local sealife. Try your hand at astronomic navigation—which sailors have used for thousands of years—by looking up at the top floor's nifty celestial dome ceiling.
