Information

Chirk Aqueduct carries the Llangollen Canal over the Ceiriog Valley, with the river below forming part of the border between Wales and England. The aqueduct was built between 1796 and 1801 by Thomas Telford during the construction of the then Ellesmere Canal. The Pontcysyllte Aqueduct three miles to the north was also later built by Telford for the same canal.

Chirk Aqueduct’s ten arches span a total length of 220m, at a height of 21m above the River Ceiriog. The waterway is contained by a cast-iron trough between the stone side walls.

Alongside the aqueduct runs a complementary masonry arched viaduct, built by Henry Robertson in 1846-1848 for the Shrewsbury and Chester Railway. At the Welsh end of the aqueduct, the canal continues northwards through the 421m-long Chirk Tunnel, built in 1794-1802.

Looking south.  Symbolising the supremacy of the railways over the canals, the viaduct was built 9 metres taller than the aqueduct.

    • Glad you liked it, Iain. Chirk had been my own list for a few years! I don’t pass that way very often, but luckily this time I did manage to get a chance to check out the aqueduct (and, more importantly, the tunnel) 🙂
