Dunvant (Welsh: Dyfnant) (Dyfn - deep; nant - stream or brook) is a suburban district and community (parish) in the City and County of Swansea, Wales, and falls within the Dunvant ward. It is situated in a valley some 4.5 miles west of Swansea city centre.
Dunvant started out as a small village based around the coal industry. The area between Dunvant and Gowerton was once quite heavily industrialised. with four nearby collieries Killan, Bishwell, Bryn Mawr and Dunvant. Bishwell and Bryn Mawr to the south of Gowerton were short-lived and closed in the 1870s. However, the collieries in Dunvant have a longer history. Dunvant closed again in 1914. Killan ceased operations in 1925 following the disaster of 1924 in which five men were killed. At its peak it employed 900 men. Other industry included the Penlan (Dunvant) Brickworks and Quarry which although long since derelict is now an area of conservation and ecological diversity.
Development of this part of the South Wales Coalfield was due to the proximity of the Central Wales Line, which first opened to passengers in 1867 taking people from Swansea Victoria station via Blackpill through to Gowerton and beyond. At its peak, the railway carried up to 80 trains a day including express trains to Shrewsbury. Houses in the area sprung up in the form of ribbon development along the roads leading to the area in the early 1920s and 1930s. However, it was in the 1960s that larger housing estates appeared, creating the sub-urban area forming Dunvant today.
