Following the recitation of the 48th chapter of the Muslim holy book of Quran, Surah Al-Fath -- meaning Victory or Triumph -- in Hagia Sophia Grand Mosque, the celebrations continued with the virtual sky mapping show that was used for the first time at Galata Tower and Hagia Sophia, a symbol of the conquest.
The image of Fatih Sultan Mehmed Han (Mehmed the Conqueror) -- who conquered Istanbul at the age of 21, and turned the Ottomans into a world empire -- on horseback was also featured in the show.
Earlier, Communications Director Fahrettin Altun on Twitter said Istanbul will celebrate its holiday "with all its splendor."
