Hamm's Brewery Caves

Underneath the currently abandoned Hamm's Brewery, there is a curious network of caves, mostly long tunnels separated into rooms by brick walls. There are two main branches running at right angles to each other and a few side branches, one of which has a hole under a cement wall leading to another cement wall which might have connected to more cave at one point. The whole place has a faint odor of sewage. Graffiti near the entrance prominently labels the place as "Hamm's Caves."
