Hellinikon Olympic Complex
The Hellinikon Olympic Complex is situated at Hellinikon on the east coast of Greece south of Athens, approximately 16 kilometres from the Olympic Village. It was built on the site of the former Ellinikon International Airport for the staging of the 2004 Summer Olympics and 2004 Summer Paralympics. It consists of 5 separate venues.
Olympic Canoe/Kayak Slalom Centre
Olympic Hockey Centre
Olympic Baseball Centre
The Olympic Baseball Centre in Athens consists of two Baseball stadiums. It was the site of the Baseball games at the 2004 Summer Olympics in Athens, Greece. The larger stadium seats 8,700 fans-though only 6,700 seats were made publicly available during the Olympics; the smaller stadium seats 4,000 spectators, though only 3,300 seats were made publicly available during the Games. The facility had to be constructed with significant foreign help in the design, as there were only a handful of dusty baseball diamonds in the whole of Greece before the 2004 Olympics were awarded to Athens in 1997. Construction on the facility was completed on February 27, 2004, and it was officially opened on August 12, 2004, a day before the Opening Ceremonies.
During the 2004 Summer Paralympic Games, the Olympic Baseball Centre was the venue for Archery.
Olympic Softball Stadium
Hellinikon Indoor Arena
The Indoor arena is an arena adjacent to the Fencing Hall. It hosted the Basketball preliminary matches and the Handball finals at the 2004 Summer Olympics in Athens, Greece. The facility seats 15,000  spectators for basketball, although only 10,700 seats were made publicly available during the Olympics - and seats 13,500 fans for handball - though only 10,300 seats were made publicly available during the games. The facility was completed on May 31, 2004 and officially opened on July 30, 2004.
During the 2004 Summer Paralympic Games, the Indoor Arena was the venue for Wheelchair rugby.
