This low-lying green island in Cork Harbour was once an important part of the port's defences, topped by an 18th-century artillery fort. In the second half of the 19th century, and again during the Irish War of Independence, it served as a prison and internment centre, gaining the nickname 'Ireland's Alcatraz'. Today you can enjoy a self-guided walking tour of the island and its fortifications, or pay more for a guided tour (€13.50/8.50); the ferry (www.spikeislandferry.com) from Kennedy Pier, Cobh, is included in price.
