You step off an air-conditioned minibus into the cool hush of stone: the Castellana Caves open like a hidden city carved by water, their caverns casting blue-gray shadows while droplets still run slow along stalactites. Later the Mediterranean brightens—Polignano a Mare’s white cliffs cut into the sea, and a small open boat slips into grotto mouths where light filters through aquamarine water.
