 After the fall of the city, his son and successor Orhan made Bursa the first official Ottoman capital and it remained so until 1366, when Edirne became the new capital.As a result, Bursa holds a special place in Ottoman history as their founding city, and also as the birthplace of Ottoman architecture (Bursa Grand Mosque (1399), Bayezid I Mosque (1395), Hüdavendigar Mosque (1385), and Yeşil Mosque) (1421).During his reign Orhan encouraged urban growth through the construction of buildings such as imarets, Turkish baths, mosques, inns and caravanserais, and he also built a mosque and a medrese in what is now known as the Hisar district, and after his death was buried there in his türbe (mausoleum) next to his father.
