On Tuesday. Free access English Heritage managed 11-13th century castle, right next to railway station and the Grand Union canal. Built entirley from local flintstones. Only a few miles from the National Trust Ashridge estate. Edward IV granted the castle to his mother Cecily Neville, Duchess of York, in 1469. She lived here for the remainder of her life, but after her death, the castle gradually fell into decay. In 1580, Elizabeth I leased the Manor of Berkhamsted, including the ruined castle and the deer park, for the nominal rent of one red rose to Sir Edward Carey, Keeper of the Queen’s Jewels.
