In its 70 miles the River Dee rises in Snowdonia and passes through England and Wales, marking the border in places, before discharging into the Irish Sea. This photograph was taken from a bridge in the Welsh town of Llangollen and illustrates its rocky passage through the settlement. The outcropping limestone in the valley made it easier to erect a bridge over the river at this point, and the town and its castle grew up around the crossing.
