El Modelo prison has a number of courtyards, outdoor spaces that were designed for soccer or other recreational activities. They are paved. In the video from the drone I saw that the space was crowded with people. At either end, there were makeshift structures. Made from pallets, scrap wood, and roofed with corrugated sheet metal, these were the only cells some of the prisoners had. These were common criminals, not the high-profile cartel members who were housed in a maximum-security VIP building. High ranking members of both factions lived on the fourth floor of their respective wings and controlled their half of the prison from there.
