Explorer Castellana Grotte

The Castellana Caves are a limestone cave system in the Murge plateau of Apulia, explored from 1938 by the speleologist Franco Anelli. Guided tours begin in La Grave, a chamber about 60 m deep lit through a natural opening in its roof, and follow either a 1 km route or a 3 km route that ends in the Grotta Bianca, lined with white calcite.

The Trullo Sovrano is a house museum in the north of Alberobello, behind the church of Saints Cosmas and Damian. It is the only trullo with an upper floor, reached by an inner masonry stair, and its main cone rises about 14 metres above a group of twelve. The oldest wing dates from the early 1600s, the rest from the 18th century.

The Trulli of Alberobello are dry-stone houses with conical roofs of grey limestone slabs that fill the Rione Monti and Aia Piccola districts of Alberobello in Apulia. Built without mortar, largely from the 17th century onwards, many are still lived in or house shops, and the ensemble has been a UNESCO World Heritage Site since 1996.
