The Irish Landmark Trust is an architectural conservation and educational organisation founded in Ireland in 1992. Similar to the British Landmark Trust, it is a registered charity which renovates buildings of historic interest and makes them available for holiday rental, while collating and sharing information on construction and restoration techniques. As of 2018, the organisation had restored over 30 properties on the island of Ireland, including a number of lighthouses and castles.
Loop Head's lighthouse cottages are Irish Landmark Trust properties.
