This fabulously grand manor house and ancestral home of the Gore-Booth family is one of the top sights of the region. Revolutionary nationalist and socialist Constance Goore-Booth (Countess Markievicz) grew up here and WB Yeats used to frequently drop by. The fabulous grounds – including the gorgeous walled alpine garden – can be wandered at will (with a ticket); access to parts of the house is by guided tour.
Take the N15 from Sligo to Drumcliff, head along the L3305 through Carney and follow the signs.
In 1918 Countess Markievicz was the first woman elected to the British House of Commons. You can explore various rooms within the house on the highly informative 45-minute tour, including the ante room, the drawing room, the dining room, the billiard room and the basement (where the kitchens were), but as it is a home in use, the upstairs rooms are inaccessible. For a cheaper ticket, you can explore the exhibition in the coach house and the grounds, but it's the house, restored at great cost by the current owners, that's worth seeing.
