Inishtrahull (Irish:Inis Trá Tholl, meaning "island of the hollow/empty beach") is the most northerly island of Ireland. It has an area of 0.34 square kilometres (0.13 sq mi) and lies about 10 kilometres (6.2 mi) north-east of Malin Head, County Donegal. The most northerly landfall of Ireland, the Tor Beg rock, is another one kilometer to the north. Inishtrahull is home to Ireland's northernmost lighthouse. The island had a resident community until 1929 and the lighthouse was manned until 1987. Today it is uninhabited and has been designated a protected area due to its wildlife.
