Velika Gorica is the largest settlement and the administrative centre of the traditional Turopolje region. Regarding the Turopolje name, among the most common opinions is that the name, meaning "Tur field", comes from an old Slavic word "tur" which means Aurochs, an ancient type of cattle with long horns, which was a symbol of fertility and the sun god. These cattle died out in the 16th century. The cattle were closely related to agriculture. Plowing had a symbolic meaning, the fertilization of Mother Earth, so these cattle were often assumed to have "sacred" characteristics. Because of its importance in the life of the plowmen, "tur" became the basis for numerous toponyms. However, as recently as the 16th century, Turopolje was called "Campus Zagrebiensis", i.e. "Zagreb field", or just "Campus" (field). At that time the name was replaced by "Tur field", i.e. Turopolje.
