Spike Island, County Cork

Spike Island (Irish: Inis Píc) is an island of 103 acres (42 ha) in Cork Harbour, Ireland. Originally the site of a monastic settlement, the island is dominated by an 18th-century bastion fort now named Fort Mitchel. The island's strategic location within the harbour meant it was used at times for defence and as a prison.

Since the early 21st century the island has been developed as a heritage tourist attraction, with €5.5 million investment in exhibition and visitor spaces and accompanying tourism marketing. There were in excess of 81,000 visitors to the island during 2019, a 21% increase on 2018 numbers. Spike Island was named top European tourist attraction at the 2017 World Travel Awards.
