Aqueduct
The village is particularly notable as the location of the world's first large-scale cast iron navigable aqueduct (52°44′13″N 2°34′04″W / 52.7370°N 2.5679°W / 52.7370; -2.5679, grid reference SJ617156). Designed by Thomas Telford, the aqueduct opened in 1797 as part of the Shrewsbury Canal. Telford built the 57 m (187 ft) cast iron aqueduct in replacement of a stone aqueduct that was originally built by Josiah Clowes, this was swept away by floods in 1795. Although the canal was abandoned in 1944 due to the increase in rail networks, the aqueduct remains and is Grade I listed and a scheduled ancient monument, situated in fields astride the River Tern. The monument is signposted and visible from the road. Clearly marked footpaths lead directly to the monument, from a small roadside car park. Telford went on to build the very much larger Pontcysyllte Aqueduct, now a World Heritage Site.
