Coole Castle Sir John MaCoghlan built Coole Castle on the banks of the Brosna in 1575. It was the last of the MacCoghlan castles to be built. He erected it as a present to his second wife Sabina O'Dallachain. Formerly, there was a mural slab in the castle with a Latin inscription translated in English as ''"“This tower was built by the energy of Sir John MacCoghlan, K.T. chief of this Sept at the proper cost of Sabina O'Dallachain on the condition that she should have it for her lifetime and afterwards each of her sons according to their seniority"''. The whereabouts of the mural is unknown at present. In his will in 1590, Sir John left Coole Castle to his widow. Over the fireplace, in its original location, in the topmost room of the castle is a plaque written in Middle Irish which reads: "SEAGHA (n) MAC (c) OCHL (ain) DO TINDSCAIN O SEO SUAS 1575" ("Sean Mac Cochlan began (this building) from this (date) 1575")
Kilcolgan Castle (Court) Terence Coghlan built Kilcolgan Castle in the early 1640s. In 1646, the Papal Nuncio was sent to Ireland; he stayed for some time in the castle and wrote admiringly of the castle demesne with its beautifully laid out gardens and peacocks strutting on the lawns. The castle continued to be in the possession of the MacCoghlans until the 18th century when it became uninhabited and fell into disrepair. The remains of the castle were demolished in 1954 and the stones used to make foundations for the power station at Lumcloon.
Gallen Priory Less than a kilometre south of the town, on the site of an ancient
monastery founded by the Welsh missionary
Saint Canoc in 492, stands Gallen Priory (formerly a
convent of the Sisters of Saint Joseph of
Cluny, now a nursing home). == Education ==
