About Trematon Castle
Trematon Castle is situated near Saltash in Cornwall, England, United Kingdom. It was the caput of the feudal barony of Trematon. It is similar in style to the later Restormel Castle, with a 12th-century keep. Trematon Castle overlooks Plymouth Sound and was built probably by Robert, Count of Mortain on the ruins of an earlier Roman fort: it is a motte-and-bailey castle and dates from soon after the Norman conquest. It occupies a sentinel position one and a half miles south-east of Trematon village (grid reference SX41065801).
