Olympic Stadium is the name usually given to the main stadium

Olympic Stadium is the name usually given to the main stadium of an Olympic Games. An Olympic stadium is the site of the opening and closing ceremonies. Many, though not all, of these venues actually contain the words Olympic Stadium as part of their names, such as stadiums in Amsterdam, Berlin, Helsinki and Paris. Olympic Stadium may also be named a multi-purpose stadium which hosts Olympic sports.^[1]

In the case of the Summer Olympic Games, athletics competitions and the football final are traditionally held in the Olympic Stadium. Exceptions to this have occurred though at the 1900, 1996 and 2016 Summer Olympics as well as at the 2010 and 2018 Summer Youth Olympic Games.

Early Winter Olympic Games often used figure skating venues as focal points. These were often designated as the Olympic Stadium, usually hosting the opening and closing ceremonies.
