The Pontcysyllte Aqueduct Conservation Area covers part of the Pontcysyllte Aqueduct and Canal World Heritage Site extending from the Llangollen canal Trevor Basin terminus in the settlement of Pontcysyllte, southwards as far as the settlement of Froncysyllte. It is located to the south west of Trevor, 6 miles south of Wrexham and 3 miles east of Llangollen. The historic A5 route from London to Holyhead, constructed by Thomas Telford, runs to the south, through the village of Froncysyllte. To the north is the A539 road to Ruabon, and the settlement of Trevor. The most prominent structure is the Pontcysyllte Aqueduct.
The conservation area is linear in form with its axis aligned approximately North - South. It incorporates key structures important in the canal development of the basin and is clearly different from the areas of 20th Century housing adjacent to the north and south ends. It includes the essential setting of the Aqueduct, the approach embankment and buildings associated with them.
The Trevor Basin Conservation Area was designated on the 6th July 1998 and extended and renamed the Pontcysyllte Aqueduct Conservation Area on 14th July 2009. The Pontcysyllte Aqueduct Conservation Area Character Assessment and Management Plan was adopted in July 2009. The Pontcysyllte Aqueduct article 4(2) direction came into effect in August 2009.
