Trevelgue Head - Porth Island
From an Account of the Exploration of Tumuli at Trevelgue, or Trevalga, in the parish of St. Columb Minor, Cornwall (The two barrows on the coast overlooking Zacry’s Islands, Watergate Bay); with Notes on a singular “Cliff Castle” on the same Estate. By William Copeland Borlase, Esq. F.S.A. 1872
Trevelgue Head – ‘Approaching it from the land side, a cultivated slope brings us down to the first ditch and rampart, the latter averaging about 8 feet in height. This line is 150 paces in length, and reaches from sea to sea, thus cutting off a piece of the promontory 250 paces long by 150 broad. On the north-east side of this enclosure stands a barrow (B), 4 feet in height, in which I discovered, on the 13th of March, 1872, a deposit of calcined bones, placed in a small cup-shaped hollow, scooped out of the natural soil and covered by a flat stone, around which were the marks of fire’.
