The complex of the City Market and Livestock Fair was realized by the German architect Walter Frese in 1928-1931, who specialized in this typology. He was invited by the mayor of Zagreb, Vjekoslav Heinzel. The southeastern peripheral zone of Zagreb at the time was planned for an industrial area, and the position along the Laščinščak stream (which determined the route of today’s Heinzelova Street) represented an important technological element for this industrial complex. Due to complementary functions, the opposite position along Heinzelova Street was chosen for the construction of the Faculty of Veterinary Medicine. The modern industrial complex of the city slaughterhouse was set back in the second plan of the plot, behind green areas. It is dominated by the high-rise water tower. Administrative and management buildings, with entrance spaces, are built along the street, marked by traditional construction with sloping roofs. Since 2000, this complex has not been in function and has since hosted a whole series of events of the (sub)cultural scene. Many reference examples in Zagreb and Europe point to the high potential of abandoned industrial buildings, so the goal is to affirm the potential of this interesting achievement of modern architecture, which, unfortunately, despite protection, is rapidly deteriorating. The Slaughterhouse is an immovable individually protected cultural property
