Grotte marine della costiera di Polignano a Mare

Sea caves punctuate the limestone cliffs of Polignano a Mare. Their openings, chambers and irregular vaults form a natural counterpart to the buildings above the coast.

Why it matters

The caves reveal the interaction of limestone, water and the sea. They also belong to the cultural identity of Polignano, where named coastal cavities have long been familiar landmarks.

What to notice

The caves differ in the shape of their entrances, the height of their vaults and their relationship with the water. Grotta Palazzese is among the best-known examples; other named cavities include the grottas delle Rondinelle and dell'Ardito. The variety of openings shows that the cliff is a changing geological surface rather than a uniform wall.

Context and history

Water circulating through limestone and marine erosion have contributed to the development of these spaces. Their individual names and associations reflect the community's relationship with its coastline. Natural formation and human familiarity together give the caves their distinctive place in the town's landscape.
