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 c. 1868. The engine house is three storeys tall and square of the Cornish type. Little is known about its history, however it is believed to have held an inverted Cornish Engine, which would be an unusual, perhaps unique feature. It ceased work in c. 1903.
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.
