Piscine Jesi in Ancona is a large, decaying indoor swimming pool and entertainment/sports complex. The main space is a high-ceilinged room, possibly a former chapel or auditorium, showing significant decay. Much of the ceiling is missing, and the floor is littered with debris. Wooden benches are broken, and a raised platform is partially collapsed. Stained-glass windows, some damaged, are visible high on the walls. A decaying organ is present. Water damage, peeling paint, and broken light fixtures are evident. Proceed with caution due to unstable floors and debris.
