It subsequently came under Roman, then Byzantine rule before it became the first capital of the Ottoman Empire in 1326 under the command of Orhan Gazi. Many important Ottoman buildings still remain in Bursa.
Known as "Green Bursa", the city is filled with gardens and parks and overlooks a verdant plain. It is situated at the centre of an important fruit-growing region. Bursa was, and still is, famous for its peaches, silk, towels and thermal springs. Make a point to try the locally invented İskender Kebab, a dish of bread, tomato sauce, strips of grilled meat, melted butter and yogurt! Candied chestnuts are another regional specialty. The tour of the city begins on the east of the city at the Yeşil Türbe (Green Mausoleum). Set in a garden and distinguished by its exterior panelling of tiles, the mausoleum holds the cenotaph of Sultan Mehmet I. Across the street, the Yeşil Mosque of 1424 reflects the new Ottoman, as opposed to Seljuk, aestheticism. A madrasah nearby completes the complex and is also home to the Ethnography Museum. Before exploring this area, stop for a glass of tea in one of the traditional tea houses. Going uphill to the east, you pass the Emir Sultan Mosque in its delightful setting and, after walking through a district of old houses, you reach the Yıldırım Beyazıt Mosque (1391).
