Aberfan (Welsh pronunciation: [ˌabɛrˈvan]) is a former coal mining village in South Wales, 4 miles (6 km) south of Merthyr Tydfil Town. The Taff Trail (locally known as the "Canal Bank" or just "the bank") runs through Aberfan from Troed-y-rhiw, to Treharris. The River Taff also flows through Aberfan.
On 21 October 1966, it became known for the Aberfan disaster, when a colliery spoil heap collapsed into homes and a school, killing 116 children and 28 adults.
There are now two schools, Ynysowen Primary School adjacent to the Grove Field and Ysgol Gynradd Gymraeg Rhyd-Y-Grug which has moved to the previously occupied Ynysowen Primary School building.
