The building itself is hostile: cracked plaster, broken windows, splintered doors and carved up desks, gloomy corridors and metal stairways, dingy cafeteria (they can eat sitting down only in 20 minute shifts) and an auditorium which has no windows. It does have murals, however, depicting mute, muscular harvesters, faded and immobile under a mustard sun.
