The OPAL detector at CERN foyer, 1990.
This sat about 100m underground, in one of four experimental halls around the LEP collider ring (the other three had different experiments/detectors). I spent a couple years doing my Ph.D research on OPAL, and worked a few shifts in this facility while it was running.
