Fort Frederick (1)
(Virgin Islands National Park)
(1718 - 1780, 1801 - 1802, 1807 - 1814), Fortsberg Hill, St. John
Only ruins remain of the fort here. It protected the approach to Coral Bay, the first Danish settlement (1718) on the island. It was overtaken and held by rebellious slaves for six months during a bloody uprising beginning in November 1733. British troops were sent from Tortola in January 1734, but were ambushed. Additional Brtitish troops from St. Kitts were sent in February 1734, but they too were withdrawn. French troops from Martinique finally put down the rebellion in May 1734. The fort was rebuilt with four bastions in 1760. Destroyed in 1780. The fort was partially rebuilt and occupied by the British in 1801 - 1802, and again in 1807 - 1814. Private property within the authorized national park boundary. Also known locally as Fort Berg. See also Island Attractions from See St.

A British five-gun shore battery (aka English Battery) (built 1807) was located 1000 feet southeast below the fort at Battery Point. A few rusty guns still remain here.

Duurloo Plantation Encampment
(1733 - 1734), Caneel Bay, St. John
The sugar plantation's great house was fortified as a stronghold for the island's Danish planters and other able-bodied men against the rebelling slaves in 1733. It was one of the very few plantations never taken by the rebels. The preserved ruins of the great house are located on the grounds of the Caneel Bay Resort. See also St. John Island History from See St.

Fort Christian (2) ?
(1734 - 1820 ?), Cruz Bay, St. John
Built after the 1733 slave revolt was finally put down. Expanded in 1825 to include a prison and courthouse. The present-day St. John Administration Building (aka The Battery) was built on the foundation ruins. This is the only remaining Danish colonial government building on the island. A museum is planned in the future after current renovations (2008). See also Island Attractions from See St.

Lind Battery

Fort Louise Augusta
(1788 - 1820's ?), Christiansted, St. Croix
A British four-gun semi-circular battery was originally located here as early as 1647, according to a Spanish map of the period. The battery was modified several times by various owners over the centuries. The adjacent barracks were built in 1788 by the Danes and named after a princess in the Danish royal house. The barracks were modified in the late 1930's as the island's first radio station. Located adjacent to the lightstation on Lagoon Bank (Altona Lagoon), at the far eastern end of the St. Croix Marina. The abandoned structure burned down in December 2011. The stone battery is still extant.

A WWII U.S. Army Air Corps field. Transferred to the U.S. Navy after the war. Renamed the Alexander Hamilton Airport, now known as the Henry E. Rohlsen Airport. Part of the former base became the University of the Virgin Islands - St. Croix in 1964. Located on the south coast east of Frederiksted.

Between 1940 and 1942, the War Department acquired approximately 2,581 acres to create Benedict Field. The Army Air Corps utilized Benedict Field as an auxiliary field for Borinquen Field in Puerto Rico. A fighter squadron was stationed at the site; it was also used as an aircraft reconnaissance outpost and training base for missions required in the Caribbean Frontier. A garrison of approximately 1,000 men were stationed at Benedict Field, and the Field included housing, a landing field with two runways, roads, utilities, storage facilities and an air warning station on a nearby hill. The site also included a bombing area for practice bombs, a small arms range and a magazine storage area. The Municipality of St. Croix currently owns the majority of the site and uses it for a municipal airport. St. Croix Alumina (a private company), US Virgin Islands Air National Guard, a highway, a horse racetrack and a motorcar drag strip also are on the site.

Fort Frederik (2) (Museum)
(Frederiksted Historic District)
(1752 - 1920), Frederiksted, St. Croix
Originally here was located British Fort St. James (1640's). Briefly taken by the Spanish in 1650, then controlled by the French. The present fort was completed in 1760. It was built primarily to prevent smuggling along the island's western shore. This fort claims to have given the first foreign salute to the U.S. flag in 1776. Here in July 1848 was proclaimed by the Danish governor the emancipation of all slaves in the Danish West Indies. U.S. Marines garrisoned the fort in 1917 as part of the Frederiksted Marine Barracks. The Marines transferred to Fort Christian (3) in 1920. The fort was later used for local government offices until 1973. Opened as a historic site in 1976. Restored to the 1840's period.

In 1653 the fort/settlement was leased from the French crown by the Sovereign Order of the Knights of Malta until about 1665, when the French crown reestablished authority and the main settlement was relocated to Bassin (present-day Christiansted). The fort and settlement was abandoned in 1695. Ruins still extant near the NPS visitor center (built in 2004).

Salt River Bay is one of only two documented sites in United States territory associated with Christopher Columbus, who came ashore here (Cape of Arrows) in November 1493. The National Park was created in 1992.

Fort Christian (1)
(1672 - 1870's, 1917 - 1931), Charlotte Amalie, St. Thomas
Attacked by the French in February 1678. A three-story oval gun tower, named Fort Trygborg, was built in 1676 near the north wall. It was demolished in the 19th century. The fort has been reconstructed several times over the years. It once housed the entire colony of St. Thomas in times of natural disaster. Also known as Fort St. Thomas according to a 1707 Danish map. This is the oldest extant structure in the Virgin Islands. After demilitarization it served as a police station, jail, courthouse, church, and the Governor's Residence. A clock tower was added in the late 19th century to replace the demolished north curtain wall. U.S. Marines garrisoned the fort in April 1917 as part of the St. Thomas Marine Barracks. The last Marines were withdrawn from St. Thomas Island in May 1931. The fort now houses the Virgin Islands Museum (closed since 2005). Admission fee. See also Fort Christian info from VI

(Hassel Island Historical Archive)
(1779 - 1790's, 1801 - 1802, 1807 - 1815), Hassel Island, St. Thomas
British works were located on Hassel Island in St. Thomas Harbor during a brief occupation during the Napoleonic Wars, when Denmark was allied with France. These were Fort Willoughby at Magens (or Frederik) Point, Cowell's Battery at Cowell's Point, and Fort Shipley (aka Shipley's Battery) on the highest point on the north side of the island. Barracks, magazines, a hospital, and other support buildings were also constructed. Fort Willoughby was located on the site of an earlier Danish fort named Fort Frederik (3) (or Prince Frederik Battery) (1779). Cowell's Battery was later used as a signal station for St. Thomas Harbor until the 1960's. Also on the island are ruins of a drydock once used by the Royal Navy, and a commercial marine railway and a coal and oil depot (1840 - 1960's). The island is accessible by passenger ferry. The "island" was created in 1860-65 by the Danish government by excavating out the narrow isthmus that connected the former peninsula to the mainland, and the channel was further widened in 1919 by the U.S. Army Corps of Engineers. The U.S. Navy had a naval station at Careening Cove from 1917 - 1931, reactivated 1941 - 1947 (several old buildings still extant). The island has been administered by the NPS since 1978 as a subunit of the Virgin Islands National Park. Preservation efforts began in 2007. See also Island Attractions from See St.

Battery 401 (1944 - 48, never armed) was located on Fortuna Hill (900 feet elevation) on the western slope of the main island. Possibly still exists (?).

¤¤ ALSO: Elsewhere on St. Thomas, AMTB Battery Muhlenfels Point (1942 - 1946) was located on Muhlenfels Point, three miles south of Charlotte Amalie. It has been incorporated into a scenic overlook for the adjacent Marriott Frenchman's Reef Hotel. Battery 315 was planned for "Hill 411", north of Little Coculus Bay near Frenchman's Bay (it was never built). Camp Acosta (1942 - 1944) was located four miles northeast of Charlotte Amalie. It later became a Peace Corps school. Bourne Field was originally built in 1935 by the U.S. Marines, expanded in 1941 by the U.S. Army Air Corps. It became the Harry S. Truman / Cyril E. King Airport after 1947. Part of the former base became the University of the Virgin Islands - St. Thomas in 1963. The U.S. Navy submarine base was built at Crown Bay in 1941. Navy seaplanes were based at Lindbergh Bay. The U.S. Army Signal Corps had a radio communications facility on St. Peter Mountain (aka Signal Hill) (1500 feet elevation) at Mountain Top (northwest of Charlotte Amalie). The present cell phone tower was built over the Army's underground bunkers.

NOTE: Discovered by the Spanish in 1493, but never colonized. English and French settlers arrived on St. Croix (Santa Cruz) in 1625. The Dutch came in 1643. The Spanish took over St. Croix in 1650, but were driven out the same year by the French. Denmark took control of St. Thomas in 1666, St. John in 1684, and St. Croix in 1733. Formerly known as the Danish West Indies since 1754, they were purchased by the U.S. in 1917 to prevent German capture, and promptly renamed. Administered by the U.S. Navy until 1931.
