The most intact historic ruin on Tortola was built by the Dutch in the early 17th century to safeguard Road Harbour. It sits on a hill at the western edge of Road Town and is now the site of a small hotel and restaurant. The foundations and magazine remain, and the structure offers a commanding view of the harbor. COST: Free. Daily dawn-dusk.

Only remnants can be seen of this 18th-century church, which was reputedly headed by a pirate priest who used the site's high ground to spy on passing ships.

Built by the Royal Engineers in 1794, Tortola's largest fortification is now a pile of ruins, with a few walls, a cistern and an underground magazine remaining.

This archaeological site has yielded numerous objects from the Ostionoid period, between 900 to 1500 A.D.
