The campus of the University of Oregon is located in Eugene, Oregon, and includes some 80 buildings and facilities, including athletics facilities such as Hayward Field, which was the site of the 2008 Olympic Track and Field Trials, and McArthur Court, and off-campus sites such as nearby Autzen Stadium and the Riverfront Research Park. An online guide published by the University of Oregon Libraries, Architecture of the University of Oregon, describes campus buildings and provides timelines of key architectural events linked with campus history.
