The remains of the Glyn Pits colliery Numbers One and Two pits, complete with their engines, are situated just outside Pontypool.

​

The pits are placed some two and a half miles to the West of Pontypool, along the New Crumlin Road, in Gwent, on the north side of the mountain known as Mynydd Maen, or 'Stony Mountain'. Approach on foot is by climbing the old tram-road from the new Crumlin Road, near the village of  'Old Furnace'. while access can also be reached from the upper race end.

​

In 1852 they were referred to as the Cwm y Glyn Pits, became the Race Colliery in 1880, and finally, in 1901, they became Glyn Pits numbers One and Two, which they are today.

​

The  Electrical Pump House was, in reality, a transformer house, which was built about the late 1940s to supply electric pumps underground when it became a pumping station. These also helped to pump water from nearby Hafodyrynys Colliery until the Glyn Pits final closure in 1966.
