Rochester Castle stands on the bank of the river Medway in Rochester, Kent, in South East England. The castle was built in the 12th century which would make it over 900 years old.
It is famous for it's unique intergrity and how it was adapted over the years and how it was fully preserved.
The first Rochester castle was built soon after 1066 and was an earth and timber construction. This was entirely replaced around 1089 by a stone castle; the stone keep was then added in 1127.Various repairs and alterations were carried out over the next few hundred years, resulting in the castle today being a mixture of many building phases, like most English castles.
