Clitheroe Castle in Clitheroe, Lancashire, England is a motte and bailey castle built on a natural carboniferous limestone outcrop. It has been suggested that Clitheroe Castle may have been first built before 1086 as there is reference to the "castellatu Rogerii pictaviensis" in the Domesday Book. However, it is likely the passage refers to another castle. One alternative is that it was built around 1186 by Robert de Lacy as an administrative centre for his estates in the area but later passed by inheritance to the Crown. It consists of one of the smallest keeps in the country and at one time it was surrounded by a curtain wall. It was anciently the seat of the Lords of Bowland.
