Wyllie colliery was the last pit to be sunk by the Tredegar Iron and Coal Company, and Wyllie Village was built to house many of the miners working at the pit. Sinking began at this colliery in 1924 and the first coal was brought to the surface in 1926.
Owned by Tredegar Southern Collieries Ltd. A subsidiary of T.I.C., it was named after Colonel Alexander Wyllie, a director with T.I.C.
Compared to other collieries in the area, Wyllie was considered highly mechanized, making use of modern coal cutting machines and conveyors from the very start of its life. The shafts were 626 yards deep and in 1938 there were 830 men employed at the site.
The colliery remained open for 42 years before closing in 1968, and the Inn, which was then the miners institute, became the local community center where village events were held. The restaurant, as it is now, housed the infant school, and the living quarters used to be a library. The old school desks are still with us in the cellar below the restaurant. The original architect drawing, dated 1923, hangs in the dining room.
Due to the village church (which was directly opposite the Inn) being demolished in the early 90’s, it was once used by local vicar, Rev Marion Barge, for special religious occasions, and during that time it was visited by the then Archbishop of Canterbury, Rowan Williams. It finally became the Islwyn Inn in 1989.
