Eyüp Sultan Mosque in Istanbul- One of the most important mosques in Istanbul, is located on the Golden Horn. Hz. It is believed that Abu Ayyub al-Ansari, who served as the flag bearer of Muhammad, was martyred during the siege of Istanbul in the 7th century and buried here. The Eyüp Sultan Mosque, built right next to the Eyüp Sultan Tomb, was built in 1458 by the order of Fatih Sultan Mehmet, after the conquest of Istanbul.
The mosque, which hosts the sword-wearing ceremony of many Ottoman sultans, especially Sultan Mehmet the Conqueror, is visited by tens of thousands of people on weekends, religious holidays.
