Holly Bush Inn Tourist Information for Pontcysyllte & The Cefn

Welcome to the Cefn Mawr Tourist Information Centre for the Pontcysyllte Aqueduct and the Cefn Viaduct at the centre of the Pontcysyllte World Heritage Site.

We are in The Holly Bush Inn at Cefn Square in the village of Cefn Mawr, which is at the centre of the Pontcysyllte World Heritage Site and we would be glad to meet and welcome you. The Holly Bush Inn is unique in that it is built from the stone rubble produced from the construction of the Pontcysyllte Aqueduct in the late 1700’s and also from the Cefn Viaduct in the 1840’s.  So, this really is a most appropriate building for tourist information on this central section of the World Heritage Site.

The construction of the Pontcysyllte Aqueduct, which crosses the River Dee, commenced in 1795 and was completed in 1805.  The Aqueduct piers were built with Cefn Sandstone and due to the magnitude of the project, a large amount of spoil was resultant.  Some of the spoil was then used for the building of the oldest section of the Holly Bush Inn.  Come and find out the fascinating history of how and why the aqueduct was built.

The Cefn Viaduct, also crossing the River Dee, was built from Cefn Sandstone in the late 1840’s.  The Viaduct carries the Shrewsbury to Chester Railway line and eventually became a part of the Great Weston Railway.  The second oldest part of the Holly Bush Inn is built from the stone spoil left over from quarrying for the Viaduct.  The location of The Holly Bush Inn and Tourist Information Service provides an ideal viewpoint for the Cefn Viaduct, the lower Vale of the Pontcysyllte World Heritage Site and the Dee Valley.
