and development took place following World War II. Forested hills and five major mountains surround the city. The highest of the surrounding peaks is Treskavica at , followed by Bjelašnica mountain at , Jahorina at , Trebević at , and Igman the shortest at . The last four are also known as the Olympic Mountains of Sarajevo When the city hosted the 1984 Winter Olympics, venues were constructed at these mountains for many winter sports events. The city is developed within hilly terrain; there are many steeply inclined streets and residences that seem to perch on the hillsides. The Miljacka river is one of the city's chief geographic features. It flows through the city from east through the center of Sarajevo to the west part of the city, where it eventually meets up with the Bosna river. Miljacka river is also known as "The Sarajevo River". Its source (Vrelo Miljacke) is south of the town of Pale at the foothills of Mount Jahorina, several kilometers to the east of Sarajevo center. The Bosna's source, Vrelo Bosne near Ilidža (west Sarajevo), is another notable natural landmark and a popular destination for Sarajevans and other tourists. Several smaller rivers and streams, such as Koševski Potok, also run through the city and its vicinity. Cityscape Sarajevo is close to the center of the triangular shape of Bosnia and Herzegovina in southeastern Europe. The Sarajevo city proper consists of four municipalities (or "in Bosnian and Croatian: općina, in Serbian: opština"): Centar (Center), Novi Grad (New City), Novo Sarajevo (New Sarajevo), and Stari Grad (Old City), while the Sarajevo metropolitan area (Greater Sarajevo area) includes these and the neighbouring municipalities of Ilidža, Hadžići, Vogošća and Ilijaš. The Metropolitan area was reduced in the 1990s after the war and the Dayton-imposed administrative division of the country, with several municipalities partitioned along the border of the newly recognised Federation of Bosnia and Herzegovina (FBiH) and Republika Srpska (RS), creating several new municipalities which together form the city of Istočno Sarajevo in the Republika Srpska: Istočna Ilidza, Istočno Novo Sarajevo, Istočni Stari Grad, Lukavica, Pale (RS-section), and Trnovo (RS-section), along with the municipality of Sokolac (which was not traditionally part of the Sarajevo area and was not partitioned). The city has an urban area of . Veliki Park (Great park) is the largest green area in the center of Sarajevo. It's nestled between Titova, Koševo, Džidžikovac, Tina Ujevića
