The bridge was probably built in the 17th century and then radically rebuilt and widened in 1795-1796. As with many older bridges, folk tales claimed that the bridge was built by the devil or by the Romans (which an investigation by the National Trust described as "very doubtful"). During the reconstruction, a stone was found with the inscription "W M 1656" scratched on it, suggesting that the bridge is at least that old. Pont Aberglaslyn is located near the downstream end of the Aberglaslyn Pass. Although the location is rocky and the river flows through rapids upstream, it is not far above sea level. (Wikipedia)

A series of five carved chairs around Harlech. Great idea to get the children outside to find them all, with scan codes at each one for more details. I believe this is number 3 over looking Harlech Castle.

Use the cycle track next to the con, not the road as cars tend to speed.
