🗺Italy 

The Blue Grotto is a cave in the Puglia region, in southern Italy, which is known for its crystal clear water and incredible blue glow inside.

An amazing play of light and shadow is created inside the cave due to the refraction of light in the water and on the walls, which gives it a unique charm. Tourists can explore the cave by boat, enjoying the beauty of nature and the purity of the water.
