Since 2016, Spike Island has tripled its annual visitor numbers from 27,000 to 81,000, won multiple international awards and contributed more than €16m to the Cork Harbour economy. Picture: Spike Island

A new five-year business strategy is to be developed to attract further visitors to Spike Island.

This is likely to include opening up so-far undeveloped areas, including tunnels, on the island which was once the biggest prison in the world.
