Azure Window

The Azure Window natural stone arch, Gozo, Malta

Limestone covers most of Gozo, one of the three populated islands in the Maltese archipelago. Mediterranean waves relentlessly pound against the shore, carving dramatic cliffs—none more striking than those that form the Azure Window. The natural arch was created when two sea caves collapsed, leaving a relatively thin horizontal ledge as a bridge between the mainland and a tall stone outcropping.

Rock continues to fall from the underside of the arch at a rate that suggests it will collapse completely within just a few years. Given the unstable conditions, posted signs warn visitors not to walk over the top of the arch, but most any day will find thrill seekers catching the dramatic view up close—while they still can.
