Ynysfach Engine House

CF48 1AB


This beautifully restored building once housed the beam engine for the blast furnaces of the Ynysfach Ironworks. Built in the early nineteenth century as part of the Crawshay's famous "Iron Kingdom".


Grade II* Listed

History
Engine House, built in 1836 for the adjacent furnaces of Ynysfach Ironworks, a subsidiary of the successful Cyfartha works owned by the Crawshay family. The Ynysfach Ironworks were founded in 1801 when 2 blast furnaces were built to plans by Watkin George, engineer and foundry manager at Cyfarthfa from 1792. In 1836 2 more furnaces were built together with the engine house which replaced an earlier one painted by Penry Williams c1815. The new engine house contained a beam blowing engine made at the Neath Abbey Ironworks. The Ynysfach works closed in 1874 and the engine house fell into disuse. It was restored between 1986 and 1989 and converted to a heritage centre and offices. The building was formerly part of the scheduled ancient monument Gm 331, which was revised to exclude the building following its conversion to a heritage centre and offices. The heritage centre was closed at the time of survey (2002).
