GEOLOGY, BY DOCTOR BOASE.
The geology of this parish is in every respect the same as that of Trenegloss.
TREVALGA.
HALS.
Trevalga Rectory is situate in the hundred of Lesnewith, and hath upon the north the Irish Sea and Ferabery, east Minster, south and west Dundagell and St. Teth.
In the Domesday Book 1087, it was taxed by the name of Trevaga or Trevalga. In the Inquisition of the Bishops of Lincoln and Winchester 1294, Ecclesia de Trevalga, in decanatu de Minor Trigshire, was rated xxxxs. In Wolsey’s Inquisition £7. 6s. 8d. which probably was a free Chapel, erected before the Norman Conquest; since it hath not then or now admitted of any alteration of its name, though I judge from that Inquisition, that it was after the Conquest partly endowed by the Canons of the Cathedral Church of Exeter; since therein I read, Canonicus Exon. percepit de Ecclesia Trevalga vs. The parish was rated to the 4s. per pound Land Tax for one year, 1696, £59. 4s. 8d.
TONKIN.
Trevalga, in the hundred of Lesnewith, is bounded to the west by Tintagel, as it is to the north by the sea, to the east by Feraberry.
