- Markree Castle: Located near Collooney, Markree Castle is a 17th-century castle originally built by the Cooper family during the Cromwellian conquest, transformed into a Gothic Revival mansion in the 19th century by Edward Joshua Cooper, an astronomer who established the Markree Observatory.

Open year-round as a 4-star hotel (check markreecastle.ie, rooms €150–€300/night), visitors can stay in opulent rooms with historical features like mahogany staircases and stucco work, or book non-guest tours by appointment (€10–€15).

- Classiebawn Castle: Built in 1874 for Lord Palmerston, an English Prime Minister, Classiebawn Castle is a Baronial-style country house on the Mullaghmore Peninsula, constructed with Donegal sandstone. On a former O’Connor Sligo estate, it’s infamous for its connection to Lord Mountbatten, who was assassinated nearby in 1979. Privately owned, it’s a striking landmark with views of Benbulben and the Atlantic. Not open to the public due to private ownership, visitors can view the castle from a distance along the Mullaghmore Peninsula (free, year-round). Expect a 15–30 minute stop to admire its fairy-tale silhouette and coastal scenery, with information boards detailing its history. No facilities on-site; parking is limited, and an electric fence restricts close access. Nearby Mullaghmore Beach (5 minutes) or the Pier Head Hotel offer dining.

Once a Gaelic stronghold, it’s now a scenic ruin with a history of changing owners, set against the rugged Atlantic coast.

Sligo has minor castle ruins like Ballinafad Castle (16th-century, near Lough Arrow, free but heavily ruined, limited access) and Castle Dargan (18th-century estate, now a hotel, no historical tours). These are less prominent due to their condition or modern use. Lissadell House, while notable, is a 19th-century mansion, not a castle.
Sligo’s castles are notable for their diverse styles, from Markree’s luxury to Ballymote’s Norman grandeur. Parke’s and Markree are the most accessible, while Classiebawn and Enniscrone offer scenic, limited-access ruins.
