Pollatoomary

Pollatoomary is the deepest explored underwater cave in Ireland. It has been explored to an underwater depth of 113 metres (371 ft).[1][2] The explored limit of Pollatoomary is also 23 metres (75 ft) deeper underwater than that of the terminal sump in Wookey Hole Caves in Somerset, England, which previously held the record for the deepest underwater cave in Great Britain and Ireland.[1][3]
