Spike Island is a 104-acre island in Cork Harbour that has functioned as a monastery, a fortress, and a prison over its 1,300-year history. Known as 'Ireland's Alcatraz,' the site features the star-shaped Fort Mitchel, which was built by the British military in the early 19th century. The island served as a prison for both Irish revolutionaries during the War of Independence and long-term inmates until its closure as a modern penitentiary in 2004. Visitors explore a network of tunnels, exhibition spaces within former cell blocks, and military fortifications. The island is accessible via a short ferry ride from the town of Cobh.
