During the 20th century, the estate declined, the house was demolished, and the parkland became farmland. Since its collapse in the mid 1960s the monument has remained a ruined heap of stones that over the years has grown in quantity as the field in which the quoit lies has been ploughed continuously and ploughed-up stones added to the heap.
Open access and ownership by the Sustainable Trust has already increased its amenity value; however this would be significantly increased by restoration. All quoits in Cornwall are impressive monuments and many are of iconic status. The importance of Carwynnen Quoit in this respect is increased by the fact that it lies outside the main distribution of these monuments and, being close to a road and near the urban areas of Redruth and Camborne, towns that have become urbanised to the detriment of their local heritage. Since its acquisition by The Sustainable Trust, local support amongst sizeable local communities for the restoration programme has been growing. Recent improvements to the access have been part financed by Cllr. Mo Williams community fund. We are grateful to James Millett, owner of the Stennack Wood, for allowing us to remove a corner of his wall to allow access for the Hiab to move the Quoit stones.
