Pembroke Castle

Pembroke Castle () is a medieval castle in Pembroke, Pembrokeshire, West Wales. The castle was the original family seat of the Earldom of Pembroke. A Grade I listed building since 1951, a major restoration took place during the early 20th century. In 1093 Arnulf of Montgomery built the first castle at the site when he fortified the promontory beside the Pembroke River during the Norman invasion of Wales. A century later this castle was given to William Marshal by Richard I. Marshal, who would become one of the most powerful men in 12th-century Britain, rebuilt Pembroke in stone creating most of the structure that remains today. The castle is open to the public and is the largest privately-owned castle in Wales.
