As you traverse through this branch, you'll be captivated by the intricate formations that adorn the cave walls. The archaeological part of the first branch reveals a large hypogeum temple that has been used since pre-Nuraghic times. Discover remnants of oil lanterns, which were once part of the water cult rituals conducted in this sacred space.
