5. Vaillant Arena

Year Opened: 1979

Location: Davos, Switzerland

Unlike like most current arenas, Vaillant Arena was once an open ice rink. In 1970, the first attempt to cover the rink began using wooden pillars and sections of timber to form a vaulted dome celling. It was finally finished in 1979 but the sides of arena were still open. Glass panels were added in 1982 to fully enclose the arena. Raised platforms with additional standing room and modern elements have been added throughout the years, but Vaillant remains the perfect venue to pray to Lord Stanley thanks to the Basilica-style ceiling and seating.
