Gravina in Puglia

A deep limestone ravine, the gravina that gave the town its name, runs along its edge, spanned by an old bridge-aqueduct and lined with churches cut into the rock. When raiders destroyed the earlier settlements in the 5th century, people moved down into the ravine's caves, and the Norman cathedral was later built right on its rim. Gravina is also the seat of the Alta Murgia national park.

Highlights

• The bridge-aqueduct across the ravine, restored by the Orsini after 1722
• San Michele delle Grotte, a 10th-century church carved into the tuff
• The cathedral, with its 17th-century chapel jutting out over the ravine
• Fiera di San Giorgio, held every April since 1294
