Fodor's Expert Review Fort Christiansvaern

The large yellow fortress dominates the waterfront. Because it's so easy to spot, it makes a good place to begin a walking tour. In 1749 the Danish built the fort to protect the harbor, but the structure was repeatedly damaged by hurricane-force winds and had to be partially rebuilt in 1771. It's now a National Historic Site, the best preserved of the few remaining Danish-built forts in the Virgin Islands. The park's visitor center is here, and rangers are on hand to answer questions.
