Portumna Castle and Gardens, the power base of the de Burgo family for centuries, was built by the fourth Earl of Clanricarde. Its unique design combines elements of medieval and Renaissance architecture, making it a remarkable example of transitional Irish architecture from the early 1600s.

A major fire in 1826 left the castle a roofless shell, but the state began restoring it from ruin in the 1960s, with restoration efforts continuing to this day. The walk up to the castle is a dramatic one, with charming formal gardens creating an enchanting sense of the original seventeenth-century setting. The walled kitchen garden is particularly memorable, offering visitors a glimpse into the past.

Portumna Castle boasts a sensational view of Lough Derg, providing visitors with an idyllic setting to explore. The castle's ground floor is open to the public, with an exhibition that brings the story of the castle and the de Burgo family to life.

Located beside the River Shannon and Portumna Forest Park, Portumna Castle and Gardens are an excellent choice for a delightful day out. Visitors can explore the castle's rich history, marvel at its stunning architecture, and enjoy the natural beauty of the surrounding area.
