This is an active aid to navigation on an islet of the same name (Irish: Oileán an Tuí) in Killeany Bay, NE of Inishmore in County Galway. Completed in 1878, it was the last of 4 lighthouses built in the 1800s on the Aran Islands. The commissioning of Straw Island marked the culmination of a 24-yr campaign by the local islanders to have a lighthouse for safe passage into Killeany Bay and the harbor at Kilronan.
