 The Ramadan Canon, at Cairo's Citadel, believed to be the birthplace of the tradition was fired on Tuesday for the first time in nearly 30 years, wait till you hear this. The firing of the Ramadan Canon, or Amidfa Alifda, at Sundown is a tradition followed in several Muslim countries. The sound of the blast carries a special meaning for Muslim worshippers, it's echoing a simpler time before the convenience of technology to tell people when they could break their Eman Zadan, Assistant Minister of Tourism Antiquities said the restoration of the Canon was part of a planned to upgrade museums and archaeological sites, including the Citadel, called the Salahuddin al-Ayubi castle. The fortress dates from the Middle Ages and is located on the Mugatam Hills in the southeast of the Egyptian capital Cairo. Construction of the castle began in 1174 under Salahuddin, the first Sultan of Egypt. It wasn't completed in his lifetime, but after his reign it became the official residence of the rulers of Egypt until the 19th century. But how the Ramadan Canon tradition came about, this is still debated by historians and scholars the world over. In one historical account, Sultan Mamluk Kushqaddam is said to have fired the Canon to test fire it after receiving it as a gift, possibly from the Chinese as they invented the cannons around about this time. Upon test firing, the shot coincided with sunset on the first day of Ramadan in 1467 or 871 in the Islamic calendar and people thought that this was meant to be a signal to the city to break the first fast on the holy month of Ramadan. After Cairo's inhabitants thanked the Sultan for the signal, he decided to fire the Canon at sundown on every day of Ramadan and the rest, as they say, it's history.
