Pembroke ( ; ) is both a town and a community in Pembrokeshire, Wales, with a population of 7,552. The names of both the town and the county (of which the county town is Haverfordwest) have a common origin; both are derived from the Cantref of Penfro: Pen, "head" or "end", and bro, "region", "country", "land", which has been interpreted to mean either "Land's End" or "headland". Pembroke features a number of historic buildings, town walls, complexes and Pembroke Castle which was the birthplace of Henry Tudor, who became . History Pembroke Castle, the substantial remains of a stone medieval fortress founded by the Normans in 1093, stands at the western tip of a peninsula surrounded by water on three sides. The castle was the seat of the powerful Earls of Pembroke and the birthplace of King Henry VII of England. Gerald de Windsor was the first recorded Constable of Pembroke.

Monkton Priory, sited on a hill across the river from the castle, founded in 1098 by Arnulf de Montgomery and granted by him to the Benedictine order, has very early foundations and retains much of the Norman walls of the nave. The choir and sanctuary were renovated in the 19th Century.

In 1866 it became the brewery for the York Tavern which was briefly Oliver
