Today I got a great postcard from Malta! The postcard shows a nice view of the Azure Window. The Azure Window is a natural arch located on the island of Gozo in Malta. Located near Dwejra Bay, the arch was made after two sea caves collapsed. It is primarily made of Maltese limestone, which is very common along the country's coast. It is a very popular attraction in Malta, especially for scuba divers. Thanks Olga!
