Trevor, Trevor Basin & Cefn Mawr

Trevor Basin & Trevor

Trevor is one of the small villages adjacent to Cefn Mawr in the Cefn, now central to the Pontcysyllte Aqueduct World Heritage Site. It gets its name from the Trevor site which is on the northern side of the Pontcysyllte Aqueduct. In turn the Trevor Basin gets its name from Trevor Hall & Estate and Trevor Uchaf dating back to the 1500’s, the Pontcysyllte Aqueduct being of a later build at the turn of the 19th century, and the basin for the Ellesmere Canal then being cut into the land of the Trevor Estate. The broader between the Trevor Estate and the Plas Kynaston Estate was once also the parish boarder between Llangollen and Ruabon, being the Tref y nant Brook.

Trevor Hall

Trevor Hall in turn is named after the seat of the Trevor’s, one of the three principle branches of the Welsh Tribe who claimed to have descended from the Tudor Trevor’s, who had lived in and around the site for centuries. The site is an ancient one, and was known to be the home of Bishop John Trevor, who built the Llangollen Bridge in 1345. The Hall itself was largely reconstructed to its present form in the 18th century by John Lloyd of Glanhavon, Montgomeryshire, who in 1715 married Mary Trevor, heiress of the Trevor’s estate. A carved stone outside of the Hall has their initials dated 1742.

The wharf and wharehouse at Trevor Basin

Both Trevor and Cefn Mawr as villages are borne out of the Industrial Revolution, the coming of the canal and the construction of the Trevor Basin.

The Trevor Basin became an extremely important loading wharf during the eras of canals and railways, having a good interchange between the two transport systems, initially with horse drawn rail roads and tramways and later in the age of the steam with railway engines.

The Trevor Basin today provides a much needed mooring and turning facility for canal barges north of the Pontcysyllte Aqueduct, before venturing on along the narrow navigation feeder channel of the Llangollen Canal to the Llangollen Marina. The Trevor Basin has often been referred to as the “tuning fork” after its shape by locals. There are facilities here for the boater at the Trevor Basin including boat hire, boat repair, local shop, and a beer or two in the Telford or the Duke of Wellington.


Furthermore the shopping high street of Cefn Mawr is a short walk, only half a mile away and now even boasts a Tesco supermarket if required.

Start of the Plas Kynaston Canal Branch at the Trevor Basin

To the north east end (top right in above aerial photograph) of the Trevor Basin, the start of the Plas Kynaston Canal branch can be found. From this bridge it extends half a mile into Cefn Mawr. The original puddle clay bed remains intact below, ex Monsanto Chemical works site. The PKC Group would like to reinstate this canal back to Cefn Mawr when the remaining part of the works closes, terminating in a much needed additional mooring space north, of the Pontcysyllte Aqueduct. If you would like to help us with this, please, just vote on our website, and thanks from the PKC Group.

Trevor Rocks to the south west of Ruabon Mountain is a popular destination for Rock Climbers, an extensive limestone outcrop, continuing from Trevor to Worlds End, was once quarried and the stone conveyed by narrow gauge railway to the canal and Trevor Basin for export by barge to other areas such as the Shropshire plane to lime fields and increase agricultural outcrop production.


The old Trevor Mill, the remains of which can still be found by the River Dee, just down the hill from Trevor Basin, on the way to the Pont Cysyllte (bridge), lying between the aqueduct and the bridge in the woods
