Trevaunance Cove

Trevaunance Cove is a small bay on the north Cornish coast and a residential area of St Agnes, Cornwall, England, United Kingdom.

[1] The cove is of national importance for its geology, because it is part of a classical site for granite mineralisation and two ore-bearing mineral veins can be seen in the cliff.

It is listed in the Geological Conservation Review and is a Site of Special Scientific Interest (SSSI).

Five years later, at a cost of £6,000, Mr Tonkin built foundations of imported Lyas stone from Aberddaw, south Wales which was laid in hot lime.

Following further damage and erosion, by 1794 a ″jetty pier″ of local ″moorstone″ was built costing £10,000, with the expenses being covered by a company of gentlemen which traded in coal, lime, slate, etc.
