Kosančićev Venac (Serbian Cyrillic: Косанчићев Венац) is an urban neighborhood of Belgrade, the capital of Serbia. It is located in Belgrade's municipality of Stari Grad.
Kosančićev Venac is located along the elbow-shaped street of the same name, 700 meters west of downtown Belgrade (Terazije). It developed on the western ridge of the ending section of the ridge of Šumadija geological bar which extends from Terazijska Terasa "via" Obilićev Venac to Kalemegdan, which is a continuation of Kosančićev Venac and overlooks the Sava port on the Sava river, the northernmost section of the neighborhood of Savamala.
Kosančićev Venac is practically the oldest section of Belgrade outside the walls of the Kalemegdan fortress. From this point the new Serbian town, as opposed to the old Turkish one in the fortress, began expanding from 1830 along the right bank of the Sava into Savamala. Princess Ljubica's Residence was built in 1831, Cathedral Church of St. Michael the Archangel in 1840, Hotel "Staro zdanje", kafana ?, Hotel "Kragujevac" and Metropolitan seat. The greatest effect on the economic prosperity and architectural shaping of Kosančićev venac had the vicinity of the Sava port which was the major hub of the international trade in Serbia at the time. Đumrukana, the custom house in Savamala, was built in 1835 and the neighborhood's section towards it was built as the wide plateau with open storage facilities. In the area in Đumrukana's direction soon hotels, inns, stores and craft shops were built. In 1867 Emilijan Josimović devised the regulation plan for Belgrade which also covered this area. Kosančićev Venac was projected as the beginning and one of three sections of the urban settlement which will connect Terazije and Kalemegdan. All three sections are called venac (in this case: round, cyclic street, literally it is Serbian for wreath) and in 1872 named after three knights and heroes of the Battle of Kosovo: Kosančićev Venac, after Ivan Kosančić, Toplički Venac, after Milan Toplica and Obilićev Venac, after Miloš Obilić. The plan included covering the street with the rough cobblestone (kaldrma).
