The Fayrouz Agha Mosque is located in Diwan Street opposite the Tram Wai Sultanahmet station in Al Fateh district in the European section of Istanbul.
The mosque was built in 1491 by the treasury official Fayruz Agha during the reign of Sultan Bayezid II. The whole square-shaped dome was created as one-of-a-kind bursa designs. The mosque is built of broken stones and is based on an eight-sided bridge. The windows of the mosque consist of two lower and upper sections. The inscription on the mosque dates back to Sheikh Hamdallah Effendi. The bridges in the building do not contradict the classical style of Ottoman architecture.
The tomb of the builder Fayrouz Agha, which was located near the mosque in the 19th century, was demolished by order of the great Sadr Fuad Pasha during the expansion of the Diwan Street. The tomb of Fayrouz Agha, made of marble, is located in front of the wall near the minaret. It is worth mentioning that the entire cemetery was demolished during the expansion of the road.
