In the salt mine of Wieliczka in Poland this is an unusual sight – it’s a simple wooden corridor and doesn’t have anything to do with salt as far as we can see. It doesn’t make it any less cooler, though – it’s still underground and built out of wood that brings a specific atmosphere. The gate in the middle is interesting too, because what’s on the floor looks like old train tracks, but then they encounter the barrier, so they don’t seem to be used anymore. photofree exgif stockphoto
