Notes on GWERNLLWYNCHWITH COLLIERY, Llansamlet 2019
A lot of overgrown and low ruins and difficult to photograph even in mid-winter. Some of the site has been cleared but I believe the site is of special interest - following extract is from Coflein website:
Gwernllwynchwith Engine House is a ruined structure of possibly the earliest surviving rotary (as opposed to reciprocating) engine house in Britain, that was built between 1772 and 1782 to house a winding engine for the Gwernllwynchwith Colliery (NPRN 33490). The engine house was out of use by 1786. The ruin is of great importance to the history of technology, as it had previously been thought that no rotary steam engines were used before 1784 when by James Watt started to build engines for colliery winding.
