The Ljubljana Zoo is located in the southern part of the Sisenski hrib, Roznik and Tivoli Landscape Parks. It can be reached from the city center of Ljubljana, from Siska or from the Ljubljana bypass.
It is a popular excursion destination which has about 200,000 visitors every year. The zoo has about 7 kilometers of walking paths and occupies about 20 ha of land. They have been developing as a modern zoo since 1988. An interesting statue of a bull awaits us at the entrance to the zoo, which is the work of sculptor and graphic artist Janez Boljka (1931). Bolka is considered to be the originator of Slovenian surrealist sculpture, and stylistically it is one of the modern surrealists. He became best known for his iron sculpture creations, which were put together to weld old weapons and scrap iron pieces. Also known is a series of works of seated figures, mostly in small plastic. Janez Boljka made monumental plastic and interesting animal and human figures in bronze. In the 1970s, he made a cycle on the theme of the liberation struggle, followed by animal cycles (capricorns, bulls, monkeys, rhinos), to which he always returned.
In recent years, Boljka has been focusing on graphics. Color etchings and then color screen printing were created. In 1988, Janez Boljka received the Preseren Award for lifetime achievement.
