Castle Cornet: Guernsey's Historic Harbour Fortress

Castle Cornet, a prominent landmark in St Peter Port, Guernsey, has guarded the island's harbor for nearly 800 years. Built in the 13th century following the division of the Duchy of Normandy, the castle's strategic location on a former tidal island made it a vital defense. Throughout its history, Castle Cornet has been captured and recaptured by the French, played a role in the English Civil War, and served as a residence for the Governor of Guernsey, a prison, and a barracks. A major explosion in 1672 destroyed the medieval buildings, after which it was never again used as a residence. During World War II, German troops occupied the castle, making concrete modifications. In 1947, the Crown presented the castle to the people of Guernsey. Today, Castle Cornet is a popular visitor attraction with five museums: The Story of Castle Cornet, the Maritime Museum, the 201 Squadron (RAF) Museum, the Royal Guernsey Light Infantry Museum, and the Royal Guernsey Militia Museum. Visitors can explore historic gardens, including the 16th-century Sutler's Garden, Lambert's Garden, the 18th-century Governor's Garden, and the 19th-century Master Gunner's Garden. A Napoleonic cannon is fired daily at noon during the tourist season, and costumed re-enactors provide living history presentations.
