Two geological wonders sit side-by-side on the Maltese island of Gozo: the Azure Window and the Blue Hole.
The window is a towering rock formation reaching 328 feet high with a precarious table structure that makes it popular for cliff divers. Below it is another wonder with a collapsed underwater limestone cave known as the Blue Hole. It’s accessed by divers through a 262-foot tunnel, and underwater you can find a beautiful array of marine life including octopi, fire worms, and sea horses.
The Azure Window is a national landmark, and known as the setting for dramatic scenes in film and TV, most recently in Game of Thrones.
Unfortunately, the Azure Window is wearing down. In April of 2012, it got a little wider when part of it broke off. When that happens, there is a plan to rechristen it the ‘Azure Pinnacle.’
Update March 2017: The Azure Window and the Stack (Pinnacle) collapsed on March 8, 2017, after heavy storms. Officials are testing whether the Blue Hole has been affected by the collapse.
