Cornwall, England

Launceston Castle was built at Launceston, Cornwall possibly as early as 1067. The original Norman motte and bailey castle, with its wooden defences, guarded the main route into Cornwall, and became the administrative centre for the Earls of Cornwall. In the late 12th century a circular stone keep was constructed on top of the motte.

Between 1227 and 1272, Richard of Cornwall held the earldom, and during this time he made extensive alterations to the castle. A tower was built inside the keep and stone curtain walls replaced the timber palisades, with substantial gatehouses in the north and south.
