U.S. Virgin Islands
Blackbeard's Castle, St. Thomas Skytsborg Tower (meaning sky tower), was built in 1679 by the Danes as a watchtower for the harbor of Charlotte Amalie. It is located at the highest point on Skytsborg Tower Government Hill. Danish Soldiers used Skytsborg as a vantage point to spot enemy ships and protect impressive Fort Christian from attacks.
Fort Christian is at sea level, which was ideal for warding off attackers with canon fire, but did not offer a good enough view of the incoming ships before they entered the harbor. It is not known what year Skytsborg Tower took on the name of Blackbeard's Castle, but the infamous Edward Teach, commonly known as Blackbeard the Pirate, did sail the Caribbean waters in the early 1700s.
It has become part of the lore of the island that he used the Tower as a vantage point for his own treacherous purposes. Blackbeard's Castle is one of four National Historic sites in the US Virgin Islands.
