Whilst out on Monday playing South of Snowdon, we came across a dissused slate mine, and in a field nearby were a load of flat slates sunk into the ground to look like gravestones?
Anyone know what it's all about? What's the story behind it? I'm keen to find out!
The GR is (about) SH612524, in Cwm Llan about 1KM from Gladstones Rock.
