A five-acre lakeside residence, Castleterry Cottage, located on the southwestern shores of Lough Conn in Co Mayo, has been listed for sale at €950,000. The 193sq m property, which has undergone renovations since its last sale in 2022, features an original traditional cottage and a contemporary two-storey extension. The house boasts a living room with an open fire and three bedrooms, all at garden level. The property is situated at the end of a country lane in the hamlet of Terrybaun, approximately 25 minutes from Ballina.

The current owners purchased the lakeside property in 2022, as they were renovating nearby and needed a place to call home while works were being executed. It appears on the Property Price Register as having sold that year for €754,000. Now reluctantly selling, as their own home is completed, they have placed this little slice of heaven on the market seeking €950,000.

The property lies on five acres of mature and well-planted grounds, making it feel like a part of the natural setting it occupies. Nestled into mature woodlands that provide shelter from the western shores of Lough Conn, there is ample room to raise a few chickens, keep small livestock, and cultivate a vegetable garden. Owners swim in the lake, which is famed for its brown trout and salmon. It extends to 14.5km from north to south and has 14,000 acres of water – so you’ll probably never meet another soul on the lake – should fishing be your passion.

The house has new bathrooms since last purchased in 2022 and a raised south-facing balcony and deck off the open-plan living space upstairs, described as being akin to "a dream-like treehouse retreat" due to the mature trees surrounding the site. The living space, designed for both daily living and entertaining (the dining area seats 12), is warmed by a wood-burning stove, while the kitchen itself is served by a pantry, allowing the space to be streamlined and the focus to be on the views.

The property takes its name from a medieval castle, Castleterry, a ruin since the late 19th century that hides here surrounded by trees and thicket. Legend has it that a tragic romance saw a local girl elope with her lover to live at the castle. Apparently, her brothers, unhappy with their sister’s defiance of their father’s wishes, cut the head off her lover and cast it into the castle. She in turn took to the lake, never to be seen again.

While mythologies of the lake may or may not be true in terms of hounds, lovers, and brothers, there is no denying what is for sale here: a lovely rural lakeside retreat where you can fish for your supper with vegetables from your garden and enjoy the calmness and tranquillity of this undiscovered spot in north Mayo.
