Caisleán Phort Omna aka Portumna Castle and Demesne stands on the shores of Lough Derg on the River Shannon. The Castle is still an imposing example of Irish architecture of the early 17th Century. Built by Richard de Burgo, 4th Earl of Clanricarde, c.1618, the castle was the principal seat of the de Burgo family for over 200 years.

Architecturally, the building marks the transition from the medieval Tower House to the Renaissance style manor house with complimentary influences from both periods. Following a fire (which gutted the castle in 1826) and the ravages of time, the castle degenerated into a roofless shell. However, since 1968, the Office of Public Works re-roofed the building and based on extensive archaeological and historical research, other significant conservation and partial restoration works continue to be carried out by a team of skilled craftsmen.

The imposing façade of the castle faces north and is approached by a long avenue and formal gardens. The dramatic approach has three structured enclosures which contain geometric and regular plantings, and an old shrub rose garden and a walled kitchen garden, all combining to re-create a sense of the original 17th-century setting.


The ground floor of the castle is open to the public and houses an exhibition on the history and restoration of the building and the de Burgo family. The virtual reality DVD presentation adds to the display, bringing the story to life.

Portumna is an excellent area to visit. Portumna Castle is within easy access of the town's other attractions such as Lough Derg, the River Shannon and Portumna Forest Park. Activities include golfing, hiking, go-karting, various heritage sites.
