Glenquin Castle

Glenquin Castle is located in Glenquin, County Limerick, Ireland. The castle visible today was built by the Irish Ó hAilgheanáin family in the mid-15th century on land that had hosted a structure since at least the late 10th century.

The earliest recorded site dates back to AD 983, suggesting this location has long been of strategic importance. In 1462, the Ó hAilgheanáin (O’Hallinans) constructed the six-storey tower house that stands as the core of Glenquin Castle. During the latter half of the 16th century, control of the castle shifted due to regional conflicts. Around 1569, it was taken by the Uí Briain (O’Briens) and soon after became a stronghold for the Geraldines during the Desmond Rebellions, a series of uprisings against English rule.

In 1571, following these rebellions, the English Crown confiscated lands held by the Geraldines, including Glenquin Castle. The castle then endured partial demolition under the direction of Walter Raleigh, a prominent English officer. Ownership passed through several hands in the following decades: the Hungerford family acquired it by 1587, followed by Sir William Courtenay in 1591, and Captain Collum in 1595.

Two centuries later, in 1840, William Courtenay, the 10th Earl of Devon, undertook restoration works on the castle, preserving its structure. In 1916, during the events of the Easter Rising, Glenquin Castle served as a gathering point for about 300 Irish Volunteers, though no fighting took place there. A further restoration occurred in the 1980s, after which the Office of Public Works took responsibility for maintaining the castle.
