This apparently coffin shaped corridor is hewn from the rock on top of which Carreg Cennen Castle stands on the edge of the Brecon Beacons in Carmarthenshire, South Wales. It leads down to a cave that must have provided either a fantastic fridge or an excellent dungeon  for the occupants of the past.

And today one of my photos of the castle has been posted as part of the Monochrome Madness series by Leanne Cole Photography 🙂
