The tombs of Osman I and Orhan I stand on the terrace in Tophane, looking out over the city the first Ottoman sultans seized from the Byzantines. They are modest by later Ottoman standards — silver-grilled cenotaphs in small domed rooms — but their historical weight is considerable. This is the dynasty's starting point.
Osman I's tomb occupies what was originally a Byzantine chapel (Ayios Elias), converted after the Ottoman conquest. Orhan's tomb is in the adjacent building. The terrace between them is one of the best viewpoints in Bursa, particularly in the late afternoon when the city below is catching the last light. The surrounding park is well kept and peaceful, and a popular spot for locals in the evening.
