Left: A medium storage chamber with access to an interconnecting steam tunnel at ceiling height. This room also has various smashed toilets. Why?

Center: Steps go past a +-intersection, left goes deeper, right goes to utility tunnels for the brewery, forward used to go to the brewery basement… it’s now backfilled. Left from the backfill is a small hallway; see ‘Backfill Self Portrait’. Center-Right: Utility tunnels tie knots between the brewery’s demolished basement and its caves. Right: Most of the storage volume is in large chambers down this causeway.
