The Ditch around the Motte, between the Motte and the Bailey.
Motte of Urr is one of the better preserved Motte and Bailey Earthworks in the UK. Even though the cows call it home now, you can see all the features quite clearly, when you remember the layout of a typical Motte and Bailey Fort.
The placement of the fort is close to the river and strategically placed with a view both up and down the valley.
