The Panathenaic Stadium or Kallimarmaro "beautiful marble" is a multi-purpose stadium in Athens, Greece. One of the main historic attractions of Athens, it is the only stadium in the world built entirely of marble. A stadium was built on the site of a simple racecourse by the Athenian statesman Lykourgos (Lycurgus) c. 330 BC, primarily for the Panathenaic Games. It was rebuilt in marble by Herodes Atticus, an Athenian Roman senator, by 144 AD and had a capacity of 50,000 seats. After the rise of Christianity in the 4th century it was largely abandoned. The stadium was excavated in 1869 and hosted the Zappas Olympics in 1870 and 1875. After being refurbished, it hosted the opening and closing ceremonies of the first modern Olympics in 1896 and was the venue for 4 of the 9 contested sports. It was used for various purposes in the 20th century and was once again used as an Olympic venue in 2004. It is the finishing point for the annual Athens Classic Marathon. It is also the last venue in Greece from where the Olympic flame handover ceremony to the host nation takes place. The Greek government, through crown prince Constantine, requested the Egypt-based Greek businessman George Averoff, to sponsor the second refurbishment of the stadium prior to the 1896 Olympics. Based on the findings of Ziller, a reconstruction plan was prepared by the architect Anastasios Metaxas in the mid-1890s. Darling writes that "He duplicated the dimensions and design of the second-century structure, arranging the tiers of seats around the U-shaped track.» It was rebuilt in Pentelic marble and is "distinguished by its high degree of fidelity to the ancient monument of Herodes."Averoff donated 920,000 drachmas to this project. As a tribute to his generosity, a statue of Averoff was constructed and unveiled on 5 April 1896 outside the stadium. It stands there to this day. The stadium held the opening and closing ceremonies of the 1896 Olympics. On 6 April (25 March according to the Julian calendar then in use in Greece), the games of the First Olympiad were officially opened; it was Easter Monday for both the Western and Eastern Christian Churches and the anniversary of Greece's independence. The stadium was filled with an estimated 80,000 spectators, including King George I of Greece, his wife Olga, and their sons. Most of the competing athletes were aligned on the infield, grouped by nation. After a speech by the president of the organizing committee, Crown Prince Constantine, his father officially opened the games. The stadium also served as the venue for Athletics, Gymnastics, Weightlifting and Wrestling.
