Lammerside Castle was originally built in the 12th. century and then strengthened in the 14th. century as a pele tower. It was used by the Wharton family until the 17th. century until they moved to Wharton Hall, a fortified Manor House, closer to Kikrby Stephen.
It can be found close to the River Eden not far from Pendragon Castle. The barrel vaulted floor still survives in part. Earthworks to the North and South suggest other buildings existed.
