The Azure Window (Maltese: it-Tieqa Żerqa), also known as the Dwejra Window (Maltese: it-Tieqa tad-Dwejra), was a 28-metre-tall (92 ft) natural arch on the island of Gozo in Malta. The limestone feature, which was in Dwejra Bay close to the Inland Sea and Fungus Rock, was one of the island's major tourist attractions until it collapsed in stormy weather on 8 March 2017. The arch, together with other natural features in the area, has appeared in a number of international films and media productions. The rock formation, which consisted of a pillar rising from the sea joined to the cliff by a horizontal slab, was created by the collapse of a sea cave, probably during the 19th century. The final collapse followed a century of natural erosion, during which large sections of the limestone arch had broken off and fallen into the sea.
