Are any of you familiar with Park Gwyn mine.
The grid reference location on this site seems to be somewhat to the south of where it is believed to be according to past OS maps, and I am told there are four shafts and an adit in close proximity there, not one as shown on most public os maps.
Wondering if nay one here has experience of this mine, and knows any further details, of location, and perhaps was involved with the capping of shafts here when the housing estate was built on top?
