Tickets for the Athens 2004 Olympics have gone on sale more than 15 months before the start of the tournament, with organisers urging spectators to buy their tickets early.
Organisers are anticipating huge demand
Athens organisers said three million tickets were available, ranging from a single 11 euros (£7.90) seat to an "Olympic experience" package valued at 71,000 euros (£51,000).
"Preliminary indications show a very high demand on tickets," said ticketing manager Maria Manolopoulou.
"National Olympic committees have already requested a significantly higher amount of tickets than what was allocated to them for the Sydney Olympic Games."
Government spokesman Telemachos Hytiris urged people not to leave applications to the last minute.
"It's still too early to say but you can be sure that there will be great demand for them so it is best to act now and book tickets early," he said.
Tickets for the most popular events such as swimming and athletics finals cost from 4 to 90 euros (£29 to £65), while a seat at the opening ceremony on 13 August starts at 100 euros (£72) and rises to 950 (£680).
Organisers say they have received four times as many applications for tickets to the opening ceremony as there are seats at the 70,000-capacity Olympic Stadium.
