Full Report for Listed Buildings
The list description is not intended to be a complete inventory of what is listed: it is principally intended to aid identification. By law, the definition of a listed building includes the entire building (i) and any structure or object that is fixed to the said building and ancillary to it and (ii) any other structure or object that forms part of the land and has done so since before 1 July 1948, and was within the curtilage of the building, and ancillary to it, on the date on which said building was first included in the list, or on 1 January 1969, whichever was later.
Date of Designation
19/01/1952
Name of Property
Pont Llanystumdwy
Unitary Authority
Gwynedd
Location
The bridge carries the main street of the village over the Afon Dwyfor.
History
The bridge was probably built first in the early C17, and was widened on the SW side in 1780 at the same time as Pont Bontfechan; it has been provided with a concrete pedestrian walkway on the NE side in the mid-late C20.
Exterior
Built of rubble stonework. Two segmental arches constructed with radial stones recessed under a regulating course, flush spandrels and parapet, all carried on a substantial water pier with a high rounded cutwater on the upstream side, and a low cutwater downstream. At the N end a further smaller segmental flood arch similarly constructed and probably to the same radius, and a further square culvert, probably for a former mill stream. A similar filled arch probably exists at the S end. The upstream cutwater has been modified to carry the concrete pedestrian walkway, with steel railings. The main arches span c10m with the crown rising 3.75m above the river. The original bridge was a total 2.8m wide, and widened in 1780 by 1.8m. The flush coped parapets 40cm thick once had inscriptions 1745, WWA 1859, D.DLL/A 12/1859 no longer visible. The present carriageway is 4m wide.
Reason for designation
Included as an imposing bridge, largely of C18 character, at the centre of the conservation area.
