Polignano a Mare, the city of the famous songwriter Domenico Modugno, climbing on a rocky outcrop overlooking the Adriatic coast, is one of the most beautiful tourist towns of the south of Bari. The houses of the old town, crossed by a maze of narrow streets, stretch out on the sea with terraces and views of picturesque cliffs. A deep knife cuts through the town, with spectacular effects. The well-kept old offers glimpses of extraordinary beauty.
