Opened by John Brogden and Sons in 1868, the ownership of Wyndham Colliery passed to Tondu and Ogmore Coal and Iron Co. by 1880 and then to North's Navigation Collieries in 1889. Finally, the pit was worked by Cory Bros. & Co. Ltd., who owned it until Nationalisation in 1947.
Wyndham, a producer of both House and Steam coal, employed 1,332 men by 1918. During 1957 the colliery was linked underground with the nearby Western Colliery.
Wyndham/Western closed in 1984. The tips have subsequently been landscaped or removed
