I took this picture last year when I was walking into the Caves of Villanova (Udine, Friuli, Italy). See those paths inside the rock was a time travel, back some thousands and thousands years back... It seemed to me that black & white was a natural way to impress this moment...
This caves are all along an itinerary of 7 km and nowadays this distance is growing with the exploration of new other caves. The first discover of the place is rather recent back in 1925 thanks to local speleologists.
