Bursa (historically also known as Prussa, Greek: Προύσα, and lateras Brusa) the first capital of the Ottoman Empire, the city is frequently cited as "Yeşil Bursa" (meaning "Green Bursa") in a reference to the parks and gardens located across its urban tissue, as well as to the vast forests in rich variety that extend in its surrounding region. The city is synonymous with the mountain Uludağ which towers behind the city core and which is also a famous ski resort. The mausoleums of early Ottoman sultans are located in Bursa and the numerous edifices built throughout the Ottoman period constitute the city's main landmarks. The surrounding fertile plain, its thermal baths, several interesting museums, notably a rich museum of archaeology, and a rather orderly urban growth are further principal elements that complete Bursa's overall picture.
