Prisoners of Metropolitan Correction Center in downtown Chicago (MCC) doing morning yoga classes on the prison rooftop (~29 floor).
The MMC seems to break away from all the past typological rules of prison. Not like the prisons in the mid-eighteens century which were built on the edge of the city, this prison is built in a crowd area in downtown, it's a concrete skyscraper in a right triangular shape with narrow and long slit windows. MCC Chicago was designed by architect Harry Weese and constracted in 1975. Weese chose the maximum five inch width for the seven-foot-high barless windows. Following an escape in 1985 bars were introduced. In 2012 two convicted bank robbers managed to create a hole and rappel 17 stories to their escape on tied bed sheets.
