Gjøvik Olympic Cavern Hall

City: Lillehammer, Norway

Year of Games: 1994

Architect: Moe–Levorsen

A hockey rink located in a mountain! 141,000 cubic meters of rock were removed to create the cavern. While the expenses were high, upkeep is low. (Think about this, no window washing costs). All that is cool, but what makes this one of the Best Buildings In Olympic History is that it is the world's latest underground cavern built for public use.
