Skipsea Castle is a Norman motte and bailey castle near the village of Skipsea, East Riding of Yorkshire, England. Built around 1086 by Drogo de Beavriere, it was designed to secure the newly conquered region, defend against any potential Danish invasion and control the trade route across the region leading to the North Sea. The motte and the bailey were separated by Skipsea Mere, an artificial lake that was linked to the sea during the medieval period via a navigable channel.
