Bursa (formerly known as Brusa or Prusa) is a city in northwestern Turkey. With a population of approximately 620,000, it is Turkey's fourth-largest city and the capital of Bursa Province. The ancient Greek city of Prusa in the 1st century BC was founded by the Bithynian king Prusias. Later it was a major city located on the westernmost extension of the famous Silk Road and the capital of the Ottoman Empire in the 14th and early 15th centuries. The city is now famous for its ski resorts (on the mountain of Uludağ), the mausoleums of Ottoman sultans, and the surrounding fertile plain. The city is also famed as the home of some important Turkish foods, especially chestnut desserts and a meat dish called iskender kebap, and is the center of the Turkish auto industry.
A bursa is also a fluid filled sac located between a bone and tendon which normally serves to reduce friction between the two moving surfaces. Inflammation or infection of the bursa leads to bursitis.
Bursa is also the center of automobile industry in Turkey. There are FIAT's and Renault's factories in Bursa.
