Cadw's description
Summary description and reason for designation
The following provides a general description of the Scheduled Ancient Monument.
The monument consists of the remains of an engine house, dating to the 18th century. It is probably associated with a new water engine pumping pit sunk in 1772 by the coal owner Chauncey Townsend. The associated colliery is known to have been out of use by 1786. Though the engine is gone, traces of various features associated with it survive inside the engine house. The building is of stone rubble with brick dressings and measures approx. 2.5m by 7m internally.
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.
