1928 Winter Olympics: The 1928 Winter Olympics, officially known as the II Olympic Winter Games (French: Les "IIes Jeux olympiques d'hiver") (German: "Olympische Winterspiele 1928") (Italian: "II Giochi olimpici invernali") (Romansch: "Gieus olimpics d'enviern 1928"), were a winter multi-sport event which was celebrated February 11–19, 1928 in St. Moritz, Switzerland.  The 1928 Games were the first true "Winter Olympics" held on its own as they were not in conjunction with a "Summer Olympics".  The preceding 1924 Games were retroactively renamed the inaugural Winter Olympics, though they had been in fact part of the 1924 Summer Olympics.  All preceding Winter Events of the Olympic Games were the winter sports part of the schedule of the Summer Games, and not held as a separate Winter Games.  These games also replaced the now redundant Nordic Games, that were held quadrennially since early in the century.
