Wikipedia says of the area

Park Hill was previously the site of back-to-back housing, a mixture of 2-3 storey tenement buildings, waste ground, quarries and steep alleways. Facilities were poor with one standpipe supporting up to 100 people. It was colloquially known as “Little Chicago” in the 1930s, due to the violent crimes sometimes committed there. Clearance of the area began on the 1930s but was halted due to World War II.
