Step inside to see how daylight enters through the many windows, then look for the curved courtyard and carved details.

An Ottoman mosque with Baroque details

Construction began in 1748 and the mosque was completed in 1755. Work started under Sultan Mahmud I and ended during the reign of Osman III. Its design marks a shift in Ottoman architecture, combining established mosque forms with Baroque influence. The mosque is associated with architects Mustafa Ağa and Simeon Kalfa.
Its name is commonly translated as “the light of Osman.” The many windows are a defining part of the building, bringing daylight into the prayer hall. The pale stone and marble help keep the interior’s appearance bright and restrained.
What to look for inside

The central dome is a prominent feature of the prayer hall, rising above supporting arches. Look for the calligraphy and the carved stone and marble details, including the mihrab. Curved lines and decorative forms distinguish the interior from the more restrained appearance of earlier Ottoman mosques.
The courtyard has a curved layout, an unusual feature in Islamic architecture. Take time to notice its proportions and the relationship between the open space and the mosque. A fountain stands in the courtyard, adding a focal point among the surrounding stonework.
A stop beside the Grand Bazaar
The mosque stands beside the main entrance area of the Grand Bazaar, in Istanbul’s Fatih district. Its setting makes it easy to combine a visit with time in the market. The streets around it are busy with shops, traders and street sellers, while the mosque grounds offer a calmer place to pause.
Visitors can enter outside prayer times, and access is generally free. Dress modestly as a courtesy. Visiting arrangements for women can change by time, so check access before arriving. If you want more context on the building’s design and history, a guided tour is another way to explore it.
