Scarbourough’s Castle Hill has been occupied for over 2500 years, but the first stone fortress on the site wasn't built until the early 12th century by William le Gros. Remains of his early building include a chapel, much altered in the 14th century, and the curtain walls which were strengthened by Henry II in the second half of the 12th century. Henry II destroyed the original gate tower and erected a more elaborate, three-storey square Keep.
