I did a lot of work in there about 3 years ago, which included minor consolidation work on the wheelpit (hence the cement bags), also bolting up the stopes and rises. It was part of my research for my book on the mines of the Rheidol valley (Rich Mountains of Lead) which was published in 2018 - that contains the full history and many photographs of the underground workings at Temple. 4 adits - two grilled, one gated, one open.
