Treffry Viaduct

Built between 1839 and 1842 by its owner Joseph Thomas Treffry, this viaduct, 90 feet high and 670 feet long, had the dual purpose of carrying both a tramway and a high level leat across the beautiful Luxulyan Valley. Located approximately 4 miles North of St Austell, it was the first large civil engineering structure of its kind to be built in Cornwall, and is now a Scheduled Ancient Monument. Although on-site parking is limited, it is an idyllic picnic spot for those who are exploring the Luxulyan Tramway Trail.
