Treffry's
Viaduct, built by the 19th Century Cornish engineer Joseph Treffry, is an engineering
wonder. Built between 1839 and 1842 the viaduct is an impressive structure,
89 feet high and 650 feet long. The viaduct's ten arches, which are 90 feet
high, have a span of 40 feet. The structure itself is 98 feet high and comprises
200,000 cubic feet of granite. It was constructed to carry horse drawn
wagons and water across the Luxulyan valley. The viaduct was also part of
a local transport system designed to carry china clay to the port of Par. Treffry
become known as the 'King of Mid Cornwall' for his remarkable achievement. This
hidden treasure was ahead of its time and was the first large granite viaduct
to be built in Cornwall. |
