Caskieben (/kæskiːˈbɛn/ kahs-KEE-ben; Scottish Gaelic: Gasach beinn "Wooded Hill") Caskieben was a palisaded tower built by the Garviach family during the 12th-century Norman expansion into Scotland. It stood on a low, circular mound surrounded by a 2 meter deep, 15 meter wide moat. This earlier wooden tower was superseded nearby by a 13th-century stone castle also named Caskieben at first, but later renamed Keith Hall. Nothing now remains of a structure, but the mound and moat are still visible.
