Cave

Ballymaglancy Cave cuts seven hundred metres through Carboniferous limestone west of Cong, keeping a dark chamber for lesser horseshoe bats rather than inviting tourists into its waterworn passages. The name preserves the Clancy or Glancy family townland, while Pollwalter points to a mill pond memory beside the entrance. Human curiosity must stop at the boundary because the bats need uninterrupted darkness, yet that restriction makes the cave more interesting: it is a living room for creatures that hear the world in echoes.
