As the first major capital of the Ottoman Empire, Bursa is home to some of Turkey’s most remarkable examples of early Ottoman religious architecture. The city’s magnificent mosques, mausoleums, and külliyes (religious and social complexes) showcase centuries of Islamic art, architectural innovation, and cultural heritage. Many of these monuments have been carefully preserved and continue to serve as important places of worship while attracting visitors from around the world.
Ulu Mosque (Bursa Grand Mosque)
Located in the heart of the city, Ulu Mosque (Ulu Cami) is one of Bursa’s most celebrated landmarks and a masterpiece of early Ottoman architecture. Commissioned by Sultan Bayezid I following the Battle of Nicopolis, the mosque was built between 1396 and 1400. Its distinctive design features twenty domes supported by twelve massive pillars, creating an impressive and spacious prayer hall.
The interior is renowned for its extraordinary collection of monumental Islamic calligraphy, regarded as one of the finest in the world. Other highlights include the beautifully carved walnut wood minbar, an exceptional example of medieval craftsmanship, and the unique marble fountain (şadırvan) positioned beneath a glass-covered central dome, allowing natural light to illuminate the interior. The mosque remains one of Bursa’s most important religious and architectural treasures.
Muradiye Külliyesi
Constructed between 1424 and 1426 by Sultan Murad II, the Muradiye Külliyesi is among Bursa’s most peaceful and historically significant religious complexes. The külliye includes a mosque, madrasa, bathhouse, charitable buildings, and beautifully landscaped gardens that create a tranquil atmosphere away from the city’s bustle.
The complex is particularly famous for its twelve richly decorated Ottoman royal tombs, where members of the Ottoman dynasty are buried. Their elegant tilework, painted decorations, and intricate architectural details make Muradiye one of the finest examples of early Ottoman funerary art.
Orhan Mosque and Külliye
Built between 1339 and 1340 by Orhan Gazi, the Orhan Mosque and Külliye ranks among the earliest Ottoman religious complexes. Originally, the külliye consisted of a mosque, madrasa, bathhouse, soup kitchen (imaret), primary school, and caravan inn, serving both the spiritual and social needs of the growing Ottoman capital.
Although modest in appearance compared with later imperial mosques, its graceful proportions and simple architectural style represent the foundations of Ottoman mosque design and provide valuable insight into the empire’s earliest period.
Yıldırım Bayezid Külliyesi
The Yıldırım Bayezid Külliyesi, built between 1390 and 1399 by Sultan Bayezid I, reflects the Ottoman tradition of combining religious, educational, medical, and charitable institutions within a single architectural complex.
In addition to its elegant mosque, the külliye includes a madrasa, a darüşşifa (hospital), a bathhouse, the sultan’s tomb, and several other public buildings. The mosque itself illustrates the evolving architectural style of the late 14th century and remains one of Bursa’s most significant historical monuments.
Yeşil Mosque (Green Mosque)
The Yeşil Mosque (Yeşil Cami) is widely regarded as one of the greatest masterpieces of early Ottoman art and architecture. Commissioned by Sultan Mehmed I and completed in the early 15th century, the mosque is renowned for its harmonious proportions and lavish interior decoration.
Its walls and mihrab are adorned with magnificent green and turquoise İznik tiles, complemented by finely carved marble, elegant calligraphy, and beautifully crafted wooden details. The remarkable artistry displayed throughout the mosque reflects the flourishing cultural achievements of the early Ottoman Empire.
Yeşil Türbe (Green Tomb)
Standing beside the Green Mosque, the Yeşil Türbe (Green Tomb) is the mausoleum of Sultan Mehmed I and one of Bursa’s most recognizable landmarks. Its striking octagonal exterior is clad in brilliant turquoise and emerald-green tiles that have become an enduring symbol of the city.
Inside, visitors can admire richly decorated tile panels, painted ornamentation, carved woodwork, and the ornate sarcophagus of Sultan Mehmed I. As part of the Yeşil Complex, the Green Tomb is considered one of the finest surviving examples of early Ottoman funerary architecture and remains an essential stop for anyone exploring Bursa’s remarkable historical heritage.
