The monument consists of the remains of an engine house, built about 1855 and used until the mine was closed in c. 1927. The engine house is built of ashlar-faced sandstone with the openings faced in the same material. In plan it measures c. 10m square. The stone fabric is substantially intact, with kneelers and coping stones surviving, but the tops of internal walls are incomplete. There are some surviving wooden window frames and internal timbers, as well as cast-iron fittings and engine mounting blocks, but the roof is missing. Debris indicates the roof was of slate with clay ridge tiles. Estimated height c. 15 M. to top of N.W. and S.E. gables.
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.
