Konjarnik is an urban neighborhood of Belgrade. It is divided between Belgrade's municipalities of Vozdovac and Zvezdara. As a large neighborhood, it has several sub-neighborhoods of its own, including Denkova Basta, Uciteljsko Naselje and Rudo. Constructing a neighborhood began in 1960s and continued in the 1970s, creating an urban connection between old Belgrade on the west and Mali Mokri Lug on the east.
Rudo is a complex of three large buildings, each with 30 floors, over 100 meters in height and, therefore, share between themselves 4th place on list of tallest buildings in Belgrade and also in Serbia. Though officially styled Rudo (after a Bosnian town), the buildings are known as the Eastern Gate of Belgrade. All three buildings are step-like and triangular shaped, built in a circle so it always visually appears than one is between the other two. Buildings, styled Rudo 1, Rudo 2 and Rudo 3, were settled in 1976, but never fully completed, as the facade wasn't finished. Since the 1990s, due to the lack of maintenance, buildings were known for elevator and water pumps problems. Reconstruction began in April 2008.
