The red circular sign with a white horizontal bar indicates a "do not enter" restriction, common in many countries. The architecture, specifically the style of the buildings and the water tanks on the roofs, strongly suggests a South American urban setting.

The architecture, featuring red brick and concrete, is very common in industrial or educational buildings in Argentina. The graffiti style and the specific model of cars parked on the street strongly reinforce my initial assessment of the Buenos Aires metropolitan area. The lighting and vegetation suggest a temperate climate consistent with the region. I am confident this is somewhere in the Greater Buenos Aires area.
