Crypt of the Original Sin
If you follow the ravine that cuts through the Murgia Plateau, you will find several natural caves that look like gaping black holes on the mountainside. There is one, however, that is of great archaeological and artistic interest - The Crypt of Original Sin. Discovered in 1963, this cave was said to be inhabited by monks in the 8th century who left beautiful frescoes. The themes of the Creator, Light and Darkness, and Adam and Eve are rendered on the rough walls of the cave.
