Llangollen Canal has 19 stone arches, each with a 45-foot (14 metre) span. Another aqueduct carries the canal over the River Ceiriog at Chirk, and there are tunnels nearby at Whitehouses, Chirk, and Ellesmere. The canal also forms the boundary on two sides of the Fenn's, Whixall and Bettisfield Mosses National Nature Reserve. In 2009 an eleven-mile section of the canal from Gledrid Bridge near Rhoswiel through to the Horseshoe Falls, which includes Chirk Aqueduct and Pontcysyllte Aqueduct, was declared a World Heritage site by UNESCO. The canal at Hurleston Junction rises from the Shropshire Union Canal main line, through four adjacent
Llangollen Canal canal by another , and by the upper lock is the grade II listed Swanley Hall, a red-brick farmhouse parts of which date from the early 16th century. Baddiley Hall, which has three storeys and an attic, and dates from the late 17th century, is set some distance back from the canal. In its grounds is the grade I listed parish church of St. Michael, the chancel of which dates from 1308, while the nave dates from 1811. Both are separated from the canal by a scheduled monument site, containing the earthworks and buried remains of an abandoned medieval village.
