Slaughterhouse of Chicago, USA. Built in 1865 and in operation for 106 years. By 1900, the 2 km² slaughterhouse housed 300,000 pigs, 75,000 head of cattle, 80,000 sheep and 6,000 horses.
With the spread of direct transportation from farmers by refrigerated trucks, the need for centralization was no longer necessary, and in 1971 the slaughterhouse was closed, and an industrial park was built in its place.
