View of the Castle of Pembroke in Pembrokeshire Wales
Artist: Robertson, Archibald
Pembroke Castle was built on a rocky outcrop surrounded by two tidal inlets. This situation made the castle almost impregnable and it became renowned as being one of the strongest fortresses in Wales. Despite its strength and size it was not built by the crown but by a private Lord- William Marshal. The large curtain wall followed the shape of the rock on which it sat and five towers were built astride the wall to protect it. Inside the inner ward the large round keep was built to a height of 22 meters, had a domed roof, four floors and battlements.
