It is built on the site of fortifications that date back to 1680 and consists of a Martello tower from 1804, later additions during the Victorian Era, and bunkers and casemates that the Germans constructed during World War II.
Following the French attempt to invade Jersey in 1781 improvements were made to island defences with Guernsey loophole towers being built, including the nearby one at Vazon.
[2] The connection between St Peter Port and the fort were improved with an upgrade of the road to military standard around 1808, using money deriving from the sale of land from the reclaimed Braye du Valle.
[3] The Martello tower was constructed in 1804 after the onset of the Napoleonic Wars, and during the tenure (1803-1813) of Lieutenant Governor General Sir John Doyle.
To simplify matters, Doyle had a local builder named Gray construct the tower, and two others, under the rubric of "fieldworks", thereby bypassing the Ordnance Corps.
Many of the bunkers, including the gun-casemate at Fort Hommet, were buried in an attempt to return the coastal landscape to its pre-war condition.
