Here's some pics from a recent visit to the Mountain Ash ROC Post. Seems to have been some kind of Fire inside as all walls show smoke damage. Post is unlocked but completely stripped and flooded with around 6 inches of water (possibly from attempts to put out Fire by local Fire Brigade) Surface features are in reasonably good condition though.
