Barmouth Bridge

Snowdonia National Park (Parc Cenedlaethol Eryri)

You're unlikely to miss Barmouth's foremost landmark: in fact, you'll probably arrive on it, by train, on foot or on two wheels. Curving scenically into town, spanning 700m of the Mawddach Estuary mouth, it was built in 1867 for the new railway and is one of the longest wooden viaducts in Britain. Originally incorporating a drawbridge, it now has a swing bridge to allow tall shipping into the estuary.
