St. Michael of the Caves Rock Complex

A special site that shows how the industrious digging of people into the Gravina Calcarenite formation shaped a unique landscape. Overlooking the ravine of Gravina in Puglia, the rock complex of San Michele delle Grotte stretches for hundreds of meters on four levels, with a main church-cave that preserves medieval frescoes and seventeenth-century decorative elements, while fossil remains of a two-million-year-old sea can be seen in the walls.

The panoramic views from its balconies are enchanting and allow us to explain the geological evolution of Puglia, of the ravines and of the Bradanica foredeep towards Matera.
