The Sanatorio is a large, decaying structure, possibly a former factory or warehouse. Upon entry, visitors will find a spacious room with several large, rusted metal tanks, some tipped over. The floor is uneven, littered with debris including bricks, wood, and metal. Sections of the building show peeling paint and exposed brick. Sunlight streams in from high windows, illuminating the otherwise dim interior. Hazards include unstable floors and scattered debris. Faded markings are visible on walls and tanks.
