Standing precariously on the edge of a cliff face just along the beach from Aldingham is the remains of a once impressive motte and bailey castle.
Michael Le Fleming built this castle, after King Henry I had granted him the lands lying eastward of Abbey Beck and southwards of the moors of Birkrigg and Swarthmoor. This land became the manor of Aldingham.
Motte and bailey castles sprung up all over Britain after the Norman Conquest to keep control of the local inhabitants.
Le Fleming faced with quite a daunting task. The northwestern corner of the kingdom was constantly disputed by England and Scotland with a mix of people from varying cultural backgrounds. There were Saxons, Norse men (Vikings) and Celts all living in the area.
