The White Tower is a central tower, the old keep, at the Tower of London in England. It was built by William the Conqueror during the early 1080s, and subsequently extended. The White Tower was the castle's strongest point militarily, provided accommodation for the king and his representatives, and housed a chapel. Henry III ordered the tower whitewashed in 1240. Today the Tower of London is a museum and visitor attraction. The White Tower now houses the Royal Armouries collections.

Colchester Castle is a Norman castle in Colchester, Essex, England, dating from the second half of the eleventh century. The keep of the castle is mostly intact and is the largest example of its kind anywhere in Europe, due to its being built on the foundations of the Roman Temple of Claudius, Colchester. The castle endured a three-month siege in 1216, but had fallen into disrepair by the seventeenth century when the curtain walls and some of the keep's upper parts were demolished; its original height is debated. The remaining structure was used as a prison and was partially restored as a large garden pavilion, but was purchased by Colchester Borough Council in 1922. The castle has since 1860 housed Colchester Museum, which has an important collection of Roman exhibits. It is a scheduled monument and a Grade I listed building.
