15th century cottage, once a courthouse, and now a tea-room owned by the National Trust next to Pont Fawr Bridge Llanrwst north Wales, UK

A ford crossed the river Conwy in this vicinity long before it was bridged. The original bridge was declared unsafe in 1626 and preparations began for its replacement, In 1634 four Lancashire stonemasons were contracted to build the new bridge. The year 1636 and the royal coat of arms are shown on a plaque on the upstream side of the bridge, which is known as Pont Fawr - large bridge.

The workmen who built the bridge inserted the keystones for the central arch upside down. This was not discovered until the opening day, when the arch collapsed. The central arch rises to c.18 metres above the water.

The bridge features cutwaters stonework shaped like a ships bow up its full height. The river is the outlet for rainwater and meltwater from across a large area of Snowdonia one of the wettest places in Britain. The western arch was rebuilt in 1703, after the original collapsed in 1702. Since then the bridge has stood the test of countless floods and the advent of motorised road vehicles.

The bridge is too narrow for two vehicles to pass eachother, and the hump-back limits forward visibility. This explains the local nickname Pont y Rhegi bridge of swearing.
