Fastnet Lighthouse is a 54-metre-tall (177 ft) lighthouse situated on the remote Fastnet Rock in the Atlantic Ocean. It is the most southerly point of Ireland and lies 6.5 kilometres (4.0 mi) southwest of Cape Clear Island and 13 kilometres (8.1 mi) from County Cork on the Irish mainland.[1] The current lighthouse is the second to be built on the rock and is the tallest in Ireland.
