They were at the time considered to be Olympic Games and were referred to as the "Second International Olympic Games in Athens" by the International Olympic Committee (IOC). However, the medals that were distributed to the participants during these Games were later not officially recognised by the IOC and are not displayed with the collection of Olympic medals at the Olympic Museum in Lausanne, Switzerland.
