Blaenau Gwent

Blaenau Gwent is a county borough in South Wales. It borders the administrative areas of Monmouthshire and Torfaen to the east, Caerphilly to the west and Powys to the north. Its main towns are Abertillery, Brynmawr, Ebbw Vale and Tredegar.

The borough was formed in 1974 as a district in the new county of Gwent. It was a merger of the Monmouthshire urban districts of Abertillery, Ebbw Vale, Nantyglo and Blaina and Tredegar, along with Brynmawr urban district and the parish of Llanelly in Brecknockshire.

It was reconstituted in 1996 as a county borough, excluding Llanelly which instead was transferred to the reconstituted Monmouthshire.
