Whilst out walking in Snowdonia recently I noticed this pill box/bunker on the shore of Llyn Ogwen, Snowdonia – on the other side of the lake from Tryfan and the A5 road. It is located at OS grid ref SH 655 605 (latitude 53.125115, longitude -4.010738).
It is constructed from concrete and stone, and was presumably fairly well camouflaged, with a layer of soil and grass/moss on the top.
Unfortunately, the entrance has been filled with boulders making access difficult/impossible.
