A boathouse is effectively a garage for a boat(s). Located at the water’s edge, such structures can be as large or small as is required for the effective storage and maintenance of the boat(s) using it. Given their waterside location, a former boathouse can make for an attractive residence if sympathetically converted.
In the grounds of Cong Castle, Lord Ardilaun (of the Guinness family) converted the first lock of the never opened Cong Canal into a boathouse. Ardilaun was something of a fan of boathouses as his estate at Saint Anne’s in Dublin also had one. There was also one on the lake at his brother’s country residence at Farmleigh.
Many boathouses are owned by the RNLI to facilitate their excellent work in assisting those in need of rescue at sea. These can be found all along the Irish coastline.
