The Ancient Agora of Athens is a flat area defined by the Sacred Rock of the Acropolis and the hill of Areopagus in the south and the hill of Kolonos Agoraios in the west. It is traversed by one of the most important ancient roads, the Panathenaic Way, which led to the Acropolis from the main gate of the city, the Dipylon Gate. This road served as the processional way for the great parade of the Panathenaic festival, which was held to honour the city patron goddess Athena.

To the north, near the middle of the open square, lay the Altar of the Twelve Gods (522/1 BC). The sanctuary was a popular place of asylum. The altar was also considered the heart of Athens, the central milestone from which distances to outside places were measured.

The most important public buildings and temples of the political, administrative and religious center of Athens were built from the 6th to the 2nd century BC at the foot of the hill of Kolonos Agoraios, along one of the busiest roads of the Agora, conventionally called West Road.

The Tholos (470 BC), a circular building, served as the headquarters of the fifty prytaneis (officials) of the Boule (senate of 500). The New Bouleuterion was the meeting place of the Boule, the law-making body that drafted law bills for subsequent discussion and approval in the Assembly (Ecclesia). The Metroon (2nd cent. BC) served both as a sanctuary of the Mother of the Gods and the archive building of the city. The Monument of the Eponymous Heroes (350 BC) was a long base for the ten bronze statues representing the eponymous heroes of the ten tribes of Athens. On the West side of the Agora there are also the remains of the Ionic Temple of Apollo Patroos (Fatherly) (325 BC), so-called because he was the father of Ion, founder of the Ionian Greeks, a tribe that included the Athenians, the cella of the small Temple of Zeus Phratrios and Athena Phratria (350 BC), who were the principle deities of the ancestral religious brotherhoods or phratries, the Stoa of Zeus Eleutherios (of Freedom), whose cult was established after the battle of Plataea in 479 BC, when the Greeks drove the Persians out of Greece, and finally the Stoa Basileios (Royal Stoa), the headquarters of the archon basileus, the official responsible for religious matters and the laws.

Overlooking the Agora from the hill to the west (Kolonos Agoraios) is the Temple of Hephaistos and Athena (second half of 5th cent. BC), popularly known as ?Theseion?.

In the northwest area were found the inscribed marble posts which were used to mark the entrances to the Agora wherever a street led into the open square. One of them with the inscription ?I am the boundary stone of the Agora? (500 BC) was found by the house of Simon the cobbler, where Socrates used to meet his pupils.

Further to the northwest starts the valley leading toward the Pnyx. Here are the complex remains of a residential and commercial area, the so-called ?Industrial District?. One larger structure, the ?Poros Building?, has been tentatively identified as the State Prison (desmoterion) where Socrates was executed.

To the south the Agora was lined with various public buildings such as the Southwest Fountain House (340-325 BC), Aiakeion -formerly identified as the Heliaia- (early 5th cent. BC), the South Stoa I (430-420 BC), the South Stoa II (2nd cent. BC), the Southeast Fountain House (530-520 BC) and the Mint (400 BC).

The Church of the Holy Apostles, dated to the years around AD 1000, belongs to the byzantine settlement of the area.

The Middle Stoa, built in the 2nd cent. BC, served a primarily commercial function. It divided the old square into two unequal halves. In the northern half of the old Agora square in the years around 15 BC, a large concert hall (odeion) was given to the Athenians by Marcus Vipsanius Agrippa. It was later adorned with a facade using pillars carved in the form of giants and tritons. North of the Odeion lay the ruins of the Doric peripteral temple of Ares, brought in pieces from Pallene and reerected in the Agora during Roman times.

Lining the east side of the Agora square is the Stoa of Attalos (159-138 BC), fully restored to serve as the site museum.

On the north side across modern Hadrian Street the excavations have revealed another large stoa identified as the Stoa Poikile (namely the Painted Stoa, from the panel paintings that once adorned it).

The Areopagus Hill was a sacred place connected to Ares and the chthonic deities of punishment and vengeance, also called ?Erinyes? (Furies) or ?Semnes? (Venerable Goddesses). It was the place of assembly of the political and judicial body of Areopagus. On the northern edge of the hill, there are the remains of four luxurious houses of the 4th-6th century AD, the so-called ?philosophical schools?, which possibly belonged to sophists. To the south of Areopagus a residential district of the ancient municipality of Kollytos was excavated by the German Archaeological Institute in the 1890s.
