Visited, with some friends. It was believed lost until afew years ago, when it was rediscovered by my friendly, famous local author.

It was a WW2 decoy site for the Rhydymwyn works (that manufactured our stocks of poison gas, to be used against the Germans, should it be used upon ourselves). Nevertheless, the Germans never discovered the works.

And on the ground, the gateway to the field, showing the area concerned:
