This grant was confirmed by Bayazid II, in recognition of the services of the nephew of Christodoulos, who built the mosque bearing that sultan's name.
The sultan rewarded Sinan by giving him the ownership of a whole street, a gift recognized by Ahmed III three centuries later.
[3] Atik Sinan designed and oversaw the construction of “one of the most important historical monuments in Istanbul” – the Fatih Mosque and its Külliye, meaning complex.
[5] The mosque had a more simple design than its grand Byzantine inspiration, as it featured only one central dome supported by a single semi-dome above the qibla.
The tombs were also significant, as they legitimized Mehmed II's claim to the title of “Kayser-i Rum (Caesar of Rome)” and further “Ottomanized the city.”[9] The Fatih Mosque's Külliye never fully succumbed to the earthquake damage that destroyed the mosque itself, and thus remains largely as Atik Sinan built it - “preserved in its original form.”[7]
