The Rustem Pasha Mosque (in Turkish: Rüstem Paşa Camii) dates to 1560. It was designed by Ottoman architect Mimar Sinan and was the first time he employed an octagonal layout.
It’s not the grandest mosque and deliberately makes no attempt to try to upstage the much larger Süleymaniye Mosque that towers on the hill above. Instead, it’s nestled in a bustling market area near the Spice Market in Eminonu. Instead, the mosque’s wealthy benefactor, Rüstem Pasha, a son-in-law of Sultan Süleyman the Magnificent (1520-1566), focused on details, especially on the interior decorations.
The colored tiles used inside are a particular highlight. They were produced during the golden age of Iznik tiling. Because red was hard to glaze into a tile at the time, its use here was particularly distinctive.
