Blackweir Bridge and Weir

Highlight • Structure

Blackweir Bridge crossing the River Taff, was designed and constructed in the 1980s by engineering students at nearby Cardiff University. The students evidently liked the feel of the earth moving under their feet, it can be a bit bouncy!

Llandaff Weir

Highlight • Natural

Llandaff Weir on the River Taff was built in the mid 1800s to help control the flow and water levels upstream. It was built in a dangerous rapid part of the river which had previously claimed several lives.
