Fort Willoughby (previously Prince Frederik's Battery) is a historic fort on Hassel Island in the U.S. Virgin Islands.
The fort was built in 1777-1780 by the Danish, who originally named it Prince Frederik's Battery. [1] At that time, Hassel Island was part of the Danish West Indies. During their first occupation of the Danish West Indies (1801-1802), the British took over the fort and renamed it Fort Willoughby. [2] The British used the fort again during their second occupation of the Danish West Indies (1807-1815). [2]
Originally, the fort consisted of parapet wall, gun platform, barracks, magazine, and storeroom, as well as kitchen, cistern, and privy. [3] Today, the remains of the fort consist of the remnants of the magazine, barracks, and cistern. [4]
Fort Willoughby is protected within the Virgin Islands National Park. [5] It contributes to the Hassel Island Historic District, [6] which has been listed on the National Register of Historic Places since 1976. [1] [7]
