Haverfordwest Castle dominates the town centre of Haverfordwest in Pembrokeshire, Wales, occupying a naturally defensive ridge position above the Cleddau River crossing. Established during Norman times in 1120 as a timber fortification by Tancred, the first lord of Haverfordwest, the castle was substantially rebuilt in stone by 1220, withstanding an attack from Llewelyn the Great. Queen Eleanor, wife of Edward I, acquired the castle in 1289 and initiated extensive construction that shaped much of the architecture visible today, which dates from 1290. Now controlled by Pembrokeshire County Council, the castle remains open to the public and benefits from partial restoration work, preserving a landmark that has defined Haverfordwest's skyline since the 12th century.
