At the 1906 Summer Olympics in Athens (often referred to as the "Intercalated Games"), an unofficial football event was held. Only four teams competed, with three of them being clubs from Greece and the Ottoman Empire. Medal tables list the gold medalist as Denmark, with the silver medals given to a mixed team from Smyrna, and the bronze medalists from Thessaloniki listed as Greece. Both were cities in the Ottoman Empire at the time.
Denmark were awarded the gold medal after the Athens team failed to appear for the second half of the final. The Athens team were subsequently invited to play off in a three-team tournament to decide second place, but refused and were promptly ejected from the competition, The Smyrna (former name of Turkish city İzmir), a team consisted of English, French and Armenian players, was also part of the competition. The Danish team was a selection of players from the Copenhagen Football Association. As this competition was not an official Olympic football tournament, no national football teams participated.
All the matches were played at Podilatodromio, which was originally a velodrome.
This venue was then demolished to build the Karaiskakis Stadium, a football stadium with capacity for 32,000.
