Ireland’s most impressive Norman keep

Nenagh Castle was built in 1216 and was the main residence for the Butler family for nearly 200 years. In the 17th century, it was captured by Owen Roe O’Neill in 1641, recaptured by Lord Inchiquin in 1642, surrendered to Lord Ireton during the Cromwellian Wars in 1651, and burned again by General Sarsfield in 1688. The circular keep is over 90 feet high and is one of the finest examples in Ireland. The ‘mock crenelations’ and the clerestory windows were added in 1861 at the instigation of Bishop Michael Flannery. Bishop Flannery’s intention was that this keep would become the bell tower of a new Cathedral (which was never built). These additions, although not historically ‘correct’ has ensured its iconic status on many logos of local clubs and businesses including Nenagh Town Council.
