 Its earliest history is debated but it is thought to be of Norman origin, probably built in the twelfth century.Property of the de Lacy family, the honour later merged with the earldom and then Duchy of Lancaster.Given to George Monck, 1st Duke of Albemarle in 1660, the castle site remained in private ownership until 1920, when it was sold to the people of Clitheroe to create a war memorial.
