Fodor's Expert Review Fort Christian
St. Thomas's oldest standing structure, this remarkable building was built between 1672 and 1680 and now has U.S. National Landmark status. Over the years, it was used as a jail, governor's residence, town hall, courthouse, and church. In 2005, a multimillion-dollar renovation project started to stabilize the structure and halt centuries of deterioration. This project is still ongoing, but you can see historic features from the outside like the four renovated faces of the famous 19th-century clock tower.
