Burncourt Castle, Fortified house in County Tipperary, Ireland.

Burncourt Castle is the ruins of a fortified house in County Tipperary with a rectangular main block and four square towers at each corner. The structure originally contained multiple fireplaces and mullioned windows, some of which remain visible.

Richard Everard began building the fortified house around 1639 on land granted when he married Catherine Plunkett in 1620; it was completed in 1641 with 26 gables and seven chimneys. In 1649, as Cromwell's Roundheads advanced, Lady Catherine burned the house herself, giving rise to the name Burned Court. Sir Richard joined the Catholic Confederates at Kilkenny in 1642, fought at the Siege of Limerick, and was captured and hanged by Henry Ireton in 1651. The house was then abandoned.

The name comes from the fire that destroyed the building and left it in ruins. Visitors can still see the remains of the massive corner towers that hint at its original power and purpose.

The ruin stands 5.4 km (3.4 mi) northwest of Ballyporeen, on the west bank of the River Tar; the M8 lies further east. Parts of the bawn and a corner turret survive nearby. Ground is uneven and foundations are exposed, so sturdy footwear helps.

Tradition holds that Burncourt was seven years in building, seven years lived in and seven days burning. Excavation found no debris from the fire, suggesting the roof slates and lead flashings were salvaged or looted for reuse elsewhere.
