Old Bishop's Palace

The Old Bishop's Palace in Llandaff, Cardiff, is a Grade I listed ruin of the medieval residence of the Bishops of Llandaff, dating to 1266 when William de Braose held the position. The distinctive twin-towered gatehouse, resembling the architecture of nearby Caerphilly Castle, is the most prominent surviving structure, while grassy mounds mark where additional buildings once stood. The palace was abandoned following Owain Glyndwr's rebellion in 1402-1405 and remained vacant until the Bishop's return to the area in 1850. Given to the City of Cardiff in 1971, the site now operates as a public garden open to visitors, offering insight into the lifestyle of medieval ecclesiastical nobility and the architectural heritage of medieval Wales.
