This colliery was sunk in 1865 by the Llynvi, Tondu and Ogmore Vale Iron and Coal Company. Following the company's bankruptcy in 1888 the Cory Brothers Limited took over and by 1913 employed 1,395 men producing steam coal. Post Nationalisation Wyndham was merged with the neighbouring Western Colliery and by 1971 employed 1,188 men producing 475,000 tons of coal making it the largest output in the South Wales Coalfield. The colliery was closed in January 1984.
