The Olympics is an international sporting event that takes place every four years. The venues for the Olympics vary depending on the host country, but typically include an ARENA, an ice rink, and a COLISEUM. An ARENA is a large enclosed space used for sports or entertainment, usually with seating for spectators. An ice rink is a flat, frozen surface used for ice skating or ice hockey. A COLISEUM is an oval or circular building used for public events, such as concerts, sports, or theatrical performances.
