Discover more about Guernsey loophole towers

The Guernsey loophole towers, also known as Martello towers, are a series of 15 defensive towers constructed between 1778 and 1779 along Guernsey's coastline. Built by the British, their purpose was to deter potential French attacks during the American Revolutionary War, when France allied with the Americans. These towers are a distinctive feature of Guernsey's coastal landscape, representing a significant part of the island's military heritage. The towers were designed with a standard layout, featuring three floors and musket loopholes on the upper levels, allowing defenders to fire upon any approaching enemy. The design was overseen by Captain Frederick Bassett. While initially armed with muskets, some towers were later reinforced with batteries and carronades during the Napoleonic Wars. During the German occupation of the Channel Islands in World War II, some towers were repurposed with machine-gun slits. Today, 12 of the original 15 towers still stand. Two of these, Petit Bôt and Rousse, feature interpretive exhibits that are open to the public. Visitors can explore these historical landmarks, learn about their construction, and imagine the lives of the soldiers who once manned them. The towers also offer stunning panoramic views of the Guernsey coastline, making them a popular destination for history enthusiasts and nature lovers alike. The surrounding areas provide opportunities for scenic walks and photography, allowing visitors to fully appreciate the beauty and history of Guernsey.
