The 12th Century Norman Keep was built in the 1180s with AD 1180-1185 often being the range quoted.
The length of the sides and height of the corner towers vary, but the Keep is approximately 100 feet square, over 80 feet high, and has walls up to 21 feet thick. It was designed by Henry II’s architect, 'Maurice the Engineer' (or mason; Latin: Ingeniator).
The North Tower and South Tower (or Flag Tower) both have spiral staircases leading from ground level up to the roof; the East Tower and West Tower do not.
To the left of the North Tower, and about two-thirds of its height, is the Forebuilding (main entrance), the largest of the period in England.
The Keep has three floors (ground, first, and second) that now contain a 2010 English Heritage representation of a medieval Royal Palace and Royal Court.
The largest pair of windows - in line with the top of the Forebuilding - are those of the second floor:
