The Panathinaikon Stadium of Athens is located north of the hill Arditos and east of Zappeion hall .The Stadium allegedly from antiquity, in medieval times had stripped completely from its marbles as the most ancient buildings in Athens. When King Otto declared Athens as the capital of Greece only two stages of the right and left fronts of the entrance remained as visible ruins of the former stage.
 Around 1856 Evangelos Zappas offered to pay the costs for restoration of the stadium. Thus the development of projects awarded to F. Bylanze, but the realization of the project in this form was cancelled. In 1874, it was built the bridge of Ilissos before the Stadium . Then the track was levelled casual and in the depth of the field where placed wooden steps for the officials. In 1895 and the following year in order to make the planned international Olympic games decided the partial restoration with marble of the Stadium by the architect A. Metaxas. George Averoff one of the most important national benefactors has offered to finance the entire cost for the completion of the project. But because the time was not sufficient until 1896 and the first modern Olympics in Athens, it was completed only part of the field and all of the first series at least from the track. The renovations were completed in 1900.
