The Kurşunlu Mosque and Complex is a magnificent example of 16th-century Ottoman architecture and one of the primary cultural gems of Eskişehir. Located in the historic Odunpazarı quarter, this architectural ensemble embodies the grandeur of the era when Turkey was at the peak of its power.

The complex owes its name to the mosque's main dome, which was traditionally covered with lead ("kurşun" in Turkish). It is not just a religious building but an entire social complex (külliye), including a mosque, a madrasa (school), a soup kitchen, a caravanserai, and a dervish lodge.
Today, the Kurşunlu Külliye is an important historical monument demonstrating the traditional organization of public space in the Ottoman Empire. Its architectural harmony and the serene atmosphere of the courtyard make it an ideal place for those who wish to experience living history.
