The Pigeon House
Many people in the HX locality go for weekend walks around Lough Gur lake. And if one takes the walk from the car park to Ash Point on the Knockadoon Hill side of the lake, one will happen across the old stone remains of a Pigeon House on one’s left-hand side.
A Pigeon House was used in medieval times to house pigeons (really MB?!) which were a source of meat, eggs, and fertiliser. The one at Lough Gur is some 400 years old, maybe much older, and the specifications are included in the information plaque next to the structure.
