What do Norwich Castle and The Tower of London have in common?
Both Norwich Castle and the Tower of London were constructed using Caen stone from Caen in France. Both structures were ordered by William to be built in the stone, imported from Northern France. The light creamy-yellow Jurassic limestone means the structures shine and can be seen for miles around. Norwich Castle was originally constructed with a flint core and the Caen stone as cladding. Over the years the outer layer has been repaired using a range of materials including, most recently, Bath Stone in the 1830s.
