Pembroke Castle (Welsh: Castell Penfro),
Pembroke, West Wales.
In 1093 Roger of Montgomery built the first castle at the site when he fortified the promontory here during the Norman invasion of Wales. A century later this castle was given to William Marshal by his friend King Richard I of England (The Lionheart). Marshall rebuilt Pembroke in stone creating most of the structure that remains today.The castle was the original seat of the Earldom of Pembroke.
The great keep, a innovative and very distinctive huge circular tower, is still known as William Marshal's Tower.
