Plaque for Tredegar ironworks engineer Rhys Davies
A plaque has been unveiled in recognition of an engineer from Tredegar who is said to have changed American history.
Rhys Davies left south Wales in 1833 to help build Tredegar Ironworks in Richmond, Virginia, which was named in his honour.
The works he built extended the American Civil War by giving the Confederate South a huge arsenal.
BBC Wales Gwent Valleys reporter Paul Heaney reports.
