Pembroke Castle is a Norman fortress founded in the late eleventh century by Roger de Montgomery, strategically positioned on a peninsula jutting into the Daugleddau estuary in Pembrokeshire. The castle's most distinctive architectural feature is its massive circular keep, constructed in the early thirteenth century under William Marshal, which rises approximately seventy-five feet and exemplifies the transitional design between earlier square keeps and later round towers. The fortress served as a crucial military stronghold throughout the medieval period, hosting royal visits and functioning as the administrative centre of the earldom of Pembroke. The substantial ruins visible today, including the keep, gatehouse, and curtain walls, testify to its importance as one of Wales's most significant medieval castles and represent a substantial investment in stone fortification by its successive lords.
