Osman Gazi Tomb
The tomb belongs to Osman Gazi, who gave his name to the Ottoman dynasty.

After conquering Bursa in 1326, Orhan Bey fulfilled the will of his father Osman Gazi (1258-1326) and buried him in the structure called "Silver Dome". The building, which Osman Gazi called the 'Silver Dome', was a Byzantine chapel whose lead-covered dome shone under the sun from far away during the siege of Bursa. The building where Osman Gazi's tomb is located today was built on the site of the chapel in the Saint Elias Monastery, which was known to have existed in this area in the 11th century. The chapel, which was converted into a mausoleum by the Ottomans, was severely damaged in the fire of 1801 and the earthquake of 1855 and was rebuilt by Sultan Abdülaziz in 1863.

The tomb has an octagonal plan and is covered with a dome.  The dome, dome skirt, and window pediments are decorated with 19th-century hand-drawn works. The wooden sarcophagus inlaid with mother-of-pearl in the middle of the tomb belongs to Osman Gazi.  Among the seventeen sarcophagi in the tomb, there are also sarcophagi belonging to Osman Gazi's son Alaaddin Bey, Orhan Bey's wife Asporça Hatun and her son İbrahim Bey, and Murad I's son Savcı Bey. 

Two works gifted to the tomb; It is a plate of the Conquest verse by calligrapher Hakkı and a painting of Bursa Yurdu embroidered with gold glitter on red satin fabric.

The tomb was repaired in 1801, 1863, 2004 and 2009.
