Trematon is a village in Cornwall, England, UK, accessible via the A38 and about two miles (3 km) from the town of Saltash and part of the civil parish of St Stephens-by-Saltash.
Trematon appears in the Domesday Book (1086) as the manor of "Tremetone",[1] at 100 households it was one of the very largest settlements in Cornwall and West Devon, larger even than nearby St Germans.[2]
William Camden says of Trematon
Trematon Castle, one and a half miles south-east of the village, stands in a sentinel position overlooking Plymouth Sound and dates from soon after the Norman conquest. It is similar in style to Restormel, being a motte-and-bailey castle with a 12th-century keep. It was built on the ruins of an earlier Roman fort.[3]
William Hals wrote that Caddock the son of Condor of Cornwall's "chief dwelling and place of residence was at Jutsworth, near Saltash and Trematon".[4]
There was previously a Wesleyan Methodist chapel at Trematon.[1]
There is a Cornish cross at a road junction between the village and the castle.[5]
Trematon Castle exists to this day and can be visited. Trematon is left of Trehan and approx 25 minutes from Tamar Bridge. Trematon Hall, a Private Georgian Period country house is set in twenty-five acres of grounds. The village also has a pub called the Crooked Inn.[6]
