This series of grottoes, 40 kilometres southeast of Bari, are the biggest ones in Italy. They are 3 kilometres long and 71 meters deep and include long underground passages and deep caves covered with hundreds of stalactites and stalagmites formed over thousands of years by water erosion of the calcareous rock.

The Archaeological Museum of Egnazia, situated beyond the walls of ancient Gnathia within the Messapian necropolis, offers a captivating journey through thirty centuries of history. From its significant Bronze Age settlement to its role as a Messapian and Roman city and later an episcopal seat in late antiquity, the museum's exceptional collection of exhibits vividly retraces the remarkable heritage of this ancient site.

In 620 AD, in the company of an angel, the prophet Mohamad took a night journey to Heaven: called Mi'raj, this episode is a key point in the Islamic tradition. Located on top of the Noble Sanctuary upland, the Dome protects the rock where this journey started. On the same rock, thousands of years before, the biblical patriarch Abraham had allegedly tried to sacrifice his son Isaac, before God told him to stop. The Dome is, according to some, the oldest existing Islamic building, and a holy place of immense importance. Byzantine artisans built it between 687 and 691, and today its golden top stands out against the cityscape. Non-Muslim visitors cannot enter the Dome, but its elegant architecture is definitely worth taking a look at.

Built to celebrate Mohamed's spiritual journey, this imposing Mosque is open to visitors of all faiths. More sober than the Dome, it was built in an early Islamic style; however, due to its complicated history, it features elements from different art styles, such as Romanesque arches, Corinthian columns, and Italian marble. The Mosque used to host the King of Jerusalem and the Templar Knights during the Crusades era.
