Trematon Castle Trematon Castle stands with an eminence rising considerably over the River Lynher, two miles southwest of Saltash and also the Tamar estuary. Robert, Count of Mortain and Earl of Cornwall most likely founded the castle. It's known to as his within the Domesday Book. In those days Trematon would be a host to some importance whereas it is now scarcely a village. The castle saw action within the Civil War and, earlier, throughout Kilter's Insurrection which started in Cornwall in 1594. The rebels laid siege towards the castle and handled to lure out and capture its defender, Mister Richard Grenville. Trematon is really a fine illustration of a motte and bailey castle. It's much more notable for that excellent upkeep of their late Norman masonry, probably the job of Henry p Dunstanville. An oblong spend keep crowns the motte along with a plain curtain surrounds the bailey. Both keep and curtain retain their crennelations, the second getting abnormally narrow merlons. Until 1897 the curtain was complete, but for the reason that year a lengthy portion was removed to provide materials for that house that stands within the bailey. Consequently, there's now a lengthy gap between your gatehouse and also the southwest corner from the bailey. In the feet from the motte is definitely an original postern. He primary entrance is thru a wonderfully maintained gatehouse added by Reginald p Valletort around 1250. Its square plan's decidedly old-fashioned at any given time when round-towered gatehouses predominated. Nonetheless, the gatehouse projects entirely outdoors the road from the curtain, to ensure that it functions like a effective flanking tower, and also the gate passage was defended by two portcullises and two gates together. The ascent with the gate passage is definitely an obstacle by itself. Note the very first arrow slits from the castle, both mix-slits around the keep parapet and also the slits with roundels within the gatehouse.
