Pembroke Castle is a medieval castle in Pembroke in West Wales. The castle is sited on a strategic rocky promontory by Pembroke River.
The first castle here was established in 1093 during the Norman invasion of Wales. It was a Norman motte and bailey with earthen ramparts and a timber palisade
The present structure owes much to William Marshal, "The Flower of Courtesy", one of the most powerful men in 12th-Century Britain. It was owned by a long succession of families and saw action in many wars and uprisings over the centuries.
Today, the castle is open to the public. It remains the largest privately-owned castle in Wales.
