The construction of the Fort Regent fortress we see today began on 7 November 1806, during the Napoleonic Wars, with the laying of a foundation stone by George Don the Lieutenant Governor of Jersey. The fort was built using local workers and men from the Royal Engineers, with an average of 800 men working at any given time. This enabled the substantial amount of work to be completed 8 years later, in 1814. It was given the name Fort Regent in honour of Prince Regent, who was King of the United Kingdom of Great Britain and Ireland at this time. The design of the fort is credited to Lieutenant-General John Humfrey, and it is thought that Lieutenant-Colonel John Evelegh would have also worked on the final plans. The fort's main features are substantial curtain walls, ditches, a glacis, redoubts, bastions, and redans (or demi-bastions). There was a parade ground in the centre, which is now built upon, and covered with a roof.
During the Occupation of the Channel Islands the German forces made some additions to the fort including flak cannons. Some of these concrete structures remain today. In December 1967 the States of Jersey made a decision to adapt the site into a leisure centre.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
