 After significant work in 1250–52 (£60 spent), 1272–1275 (£40) and 1288–1290 (£151), it is likely that the castle buildings were complete by 1300.King Henry gave Prince Edward (later King Edward I) Peveril Castle along with the County Palatine of Chester with the royal holdings in Wales and Ireland.Some of the lands, including Peveril, were made part of Eleanor of Castile's dower, to come into her possession should her husband, Prince Edward, die.
