Round 200m north west of Penventinnie

Penventinnie Round is an Iron Age oval enclosure in Cornwall, England. It stands on gently sloping ground north-west of Truro, surrounded by the Kenwyn River and its tributaries. The site has an inner earthen bank and a broad outer ditch, with an entrance on the south-west side. A second entrance on the north-east side was later added. The oval measures eighty-five metres by sixty metres inside the bank. Iron Age farmers built these ringforts from around 400 BC to protect their roundhouses and livestock. Penventinnie Round belongs to a cluster of similar sites in the area, including Higher Besore and Polstain. Nearby Bosvisack Round sits on a low hill about one kilometre to the west. The enclosure’s ditch and bank once formed a clear barrier against raids and animals. Visitors walk along the remaining bank and view the shallow ditch on the north side. The river on the east and south provides a natural defence, while the open south-west side offers easier access. The site is quiet, with no modern buildings inside, and the surrounding fields stretch away towards Truro. From the top of the bank there are wide views over the valley and the hills beyond.
