In short: Commissioned by Sultan Selim II and built by the legendary architect Mimar Sinan, the Selimiye Mosque in Edirne remains a pinnacle of Islamic design. Completed in 1575, this architectural marvel was intentionally engineered to surpass the scale of the Hagia Sophia, forever changing the landscape of Ottoman imperial building.

The Selimiye Mosque was constructed between 1568 and 1575 at the height of Ottoman power. Sultan Selim II, who had served as governor of Edirne from 1548 to 1550, chose the city for his imperial complex rather than the capital, Istanbul. Historians debate his motivations, though the decision may have been influenced by a lack of available hilltop sites in Istanbul or the fact that Selim II had not yet secured a major military victory, a traditional prerequisite for building a sultanic mosque in the capital.

Architect Mimar Sinan, who considered this his greatest work, utilized an innovative 'octagonal baldaquin' design. By supporting the massive central dome with eight pillars integrated into the outer walls, he created an interior space dominated by a single, unimpeded dome. This structural feat allowed for a diameter of 31.28 metres, which Sinan claimed was four cubits wider and six cubits higher than the dome of the Hagia Sophia. The mosque’s four identical minarets, each standing 70.89 metres tall, were positioned to frame this central dome, a departure from traditional asymmetrical layouts.

The complex, or külliye, includes madrasas, a covered market, and an elementary school. Over the centuries, the site has witnessed significant history, from the imprisonment of Baha'u'llah in the 1860s to artillery damage during the 1913 siege of Edirne. While some original features, like the courtyard fountain's canopy, are missing, the mosque remains a UNESCO World Heritage site, serving as a model for later structures like the Sabancı Merkez Mosque and the Nizamiye Mosque in South Africa.

The mosque's interior decoration reflects a blend of original 16th-century artistry and 19th-century restoration. While the Iznik tilework and marble carving are celebrated, the müezzin mahfili—a platform placed directly under the dome—remains a unique design choice that obscures the mihrab from the entrance, emphasizing the central dome's dominance. Today, the site continues to undergo comprehensive restoration to preserve its status as a masterpiece of Ottoman architecture.
