The monument consists of the remains of a steam pumping engine, dating to the 19th century. It was built in 1893 at Marine Colliery, in a chamber beneath the winding engine on the downcast shaft. The engine could deal with 50,000 gallons of water per hour when working at seven strokes per minute. It has a 68 inch low pressure cylinder with a 10 feet stroke. The engine cost £4,630 to install and was built entirely of cast iron. The engine was moved to its current location in 2003 following the construction of a new road.
The monument is of national importance for its potential to enhance our knowledge of mining in Wales. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques. An engine house may be part of a larger cluster of industrial monuments and their importance can further enhanced by their group value.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
