It was built by the Athenians, using marble from the island of Paros, to house their offerings to Apollo. What you see is a copy; the original is in the Delphi Museum. Dating from the fourth century BC, with later alterations during the Roman period, the theater could accommodate 5,000 spectators on 35 rows of stone benches.
It was built to host musical contests at the Pythian Games, which were held at Delphi from 590 BC onwards.
It was established in 1892, when the village of Kastrí, which had grown up on the site of the Temple of Apollo, was moved to a new position one kilometer west to allow excavation of the ancient site.
The wall's main face is 90 meters long and it was originally two meters taller than it is today.
The Treasury of the Athenians (built around 510 BC and re-erected 1903-06) is in the form of a Doric temple.
Delphi (Delfí), lying on the slopes of Mount Parnassus high above the Gulf of Corinth, is one of the most famous historic sites in Greece, known throughout the ancient Greek world and beyond as the sanctuary of Apollo and the shrine of his oracle.
Today a UNESCO World Heritage Site, Delphi ranks with the Acropolis in Athens, Olympia, and the island of Delos as one of the most important tourist attractions of the classical period of ancient Greece.
In winter, wealthy Athenians like to visit the mountain village of Arachova (population 800), on the north slopes of Mount Parnassus, a few kilometers east of Delphi.
Old stone buildings house old-fashioned hotels and guest houses with traditional decor, and small romantic taverns serve local specialties such as hilopites (a type of pasta) and formaéla (cheese served grilled).Its wealth of remains combines with its magnificent mountain setting and its importance in Greek mythology to make Delphi one of the high points of a visit to Greece.Delphi lies 180 kilometers northwest of Athens to which it is connected by a regular bus service.Its tiered stone seating could accommodate 500 spectators.Like the theater, it was built to host the Pythian Games, staged at Delphi from 590 BC onwards; athletic contests would have been held here.Close to the fourth-century-BC Temple of Athena, stands the Tholos, based on a circular plan with the remains of 20 Doric columns on the outside and 10 Corinthian columns in the interior.
