Following the path of the underground mine, you get to the lovers chambers. Upon arrival, you see a huge figure containing 1600 k salt, heart-shaped, carved in the early 60s by the miner Miguel Sanchez. It's a real treasure, and the reflection of the light that penetrates it makes it magical. I found a beautiful phrase on the internet: ... "IN THE NEMOCON SALT MINE IN THE HEART OF COLOMBIA THE DEPTHS OF THE EARTH REACH TO THE WORLD" ... It's a must-see.
