Warkworth Castle, Warkworth, Northumberland, England  http://www.castlesandmanorhouses.com/photos.htm  It is an example of a Norman Motte and bailey castle.  Both town and castle occupy a loop of the River Coquet, less than a mile from England&#x27;s north-east coast.  Traditionally the castle&#x27;s construction has been ascribed to Prince Henry of Scotland in the mid-12th century, but it may have been built by King Henry II of England when he took control of England&#x27;s northern counties.
