Hello there, The University here has nine buildings set around a central courtyard (Cambridge style?) about 300 metres by 100 metres, with a tunnel going in a loop beneath those buildings. The tunnel is acessable from several points - one gate at ground level, a shaft that goes to the top of a three storey clock tower, the bottom of a fire escape from a large library and various manholes. The tunnel is lit for most of it's length, the only major exception is near the clock tower, where there is a nasty drop into a shaft in the dark. At the bottom of this shaft is some obsolete (1960's) computer and telephone exchange equipment. The tunnel mainly carries airconditioning equipment, water and power. Steam isn't required in a sub-tropical city.
The university also owns a small abandoned silver mine about five kilometres from the main campus. The Mining Engineering Department maintains two galleries, two shafts and and adit from one gallery out onto the hillside. The lower levels are submerged, and all of the stopes are sealed off. Mining engineers do experiments involving ventilation, rock bolts and generally digging holes. The mine has an open day once a year with underground tours and students participating in rock drilling races (above ground on lumps of concrete. The home page for the University mine is:
There isn't much to see on the page except for a photo of the head of the main shaft -fortunately the first thing to come up, because it is a slow page.
The top of the shaft was submerged in 1974, and the mine filled up with large quantities of river mud, it took years (with student labour) to clear the bits of the mine that are in use.

There are tunnels under the University of Queensland, in Brisbane, Australia. Enter via small trapdoors in male restrooms in Forgan Smith and Goddard Buildings. Please keep me anonymous, Uni Admin does NOT like tunnelers.
