DescriptionThis three-quarter mile long deep canal cutting leading to Chirk tunnel from the north is of international importance in being part of one of the first recorded cut and fill engineering schemes whereby spoil from this feature was transported north by construction railway, or possibly boat, to build the large embankment at the south end of the Pontcysyllte Aqueduct. The Canal Act was passed in 1793 and extensive works started at Chirk and Pontcysyllte in 1795 with the canal opened north to Froncysyllte in 1801 and to below Frankton Locks to the south in 1802.
