Fort Tourgis is the largest of Alderney's Victorian-era fortifications, built between 1855 and 1860 on the northwest coast. The fort is a substantial granite structure with a long barrack block, gun batteries, and a parade ground, set into the hillside above Clonque Bay. In its heyday it could garrison hundreds of troops.
The fort has been in private ownership for years and the interior is not regularly accessible, but the exterior walls, batteries, and the approach walk along the coast make it worth visiting. The walk from St Anne takes about 30–40 minutes along the cliff path. Clonque Bay below the fort is one of Alderney's best beaches — sheltered, sandy, and not often crowded. The combination of Victorian fortifications, German concrete additions from the occupation, and the dramatic coastal setting gives the area an atmosphere that's hard to match elsewhere in the Channel Islands.
