Temple of Ares

The Southeast Temple is the modern name for an Ionic octostyle prostyle temple located in the southeast corner of the Ancient Agora of Athens. Architectural fragments from the temple enable a full, if tentative, reconstruction of its appearance.These fragments originally belonged to the Temple of Athena at Sounion at the southern tip of Attica, but they were spoliated to build the temple in the Agora in the first half of the second century AD. It was thus the last of several "itinerant temples," relocated from the Attic countryside to the Athenian Agora in the Imperial period. It is unknown which god or hero it was dedicated to. It was heavily damaged during the Herulian Sack of Athens in 267 AD and then spoliated to build the post-Herulian fortification wall.

The Southwest Temple is the modern name for a tetrastyle prostyle Doric temple located in the southwest part of the Ancient Agora of Athens. Fragments from the temple found throughout the Agora enable a full, if tentative, reconstruction of the temple's appearance. These fragments originally belonged to several Hellenistic structures and a fifth-century BC stoa at Thorikos in southeastern Attica, but they were spoliated to build the temple in the Agora in the age of Augustus. It is unknown which god or hero the temple was dedicated to. It was spoliated to build the post-Herulian fortification wall after the Herulian sack of Athens in 267 AD.

The Altar of the Twelve Gods (also called the Sanctuary of the Twelve Gods), was an important altar and sanctuary at Athens, located in the northwest corner of the Classical Agora. The Altar was set up by Pisistratus the Younger, (the grandson of the tyrant Pisistratus) during his archonship, in 522/1 BC. It marked the central point from which distances from Athens were measured and was a place of supplication and refuge. The exact identities of the twelve gods to whom the Altar was dedicated is uncertain, but they were most likely substantially the same as the twelve Olympian gods represented on the east frieze of the Parthenon: Zeus, Hera, Poseidon, Demeter, Apollo, Artemis, Hephaestus, Athena, Ares, Aphrodite, Hermes, and Dionysus, though there are reasons to suppose that Hestia may have been one of the twelve.It was formerly thought that during the Roman period, the Altar became known as the Altar of Pity (Eleos), however that altar is now believed to have been located further east in the Roman Agora. The altar was dismantled c. 267 AD.

The Altar of Zeus Agoraios (meaning Zeus of the Agora) is an altar dating to the 4th century BC located north-west of the Ancient Agora of Athens, constructed from white marble, 9m deep and 5.5m wide.It was one of the first objects to be discovered inside the Agora during the excavations of 1931. Evidence of marks done by masons from the Augustan period show that it was moved from an initial source later identified as the Pnyx located outside the ancient Agora.One of the excavators of the Agora, T. L Shear Jr., noted: it may not be coincidence that Zeus, whose special task it was to govern the political assemblies of the Athenians, should depart the Pnyx at just the time when Augustus is said to have curtailed sharply the powers of those same assemblies.

The Odeon of Agrippa was a large odeon located in the centre of the ancient Agora of Athens. It was built about 15 BC, occupying what had previously been open space in the centre of the Agora. It was a gift to the people of Athens by Marcus Vipsanius Agrippa, a Roman statesman and general.

The ancient Agora of Athens (also called the Classical Agora) is the best-known example of an ancient Greek agora, located to the northwest of the Acropolis and bounded on the south by the hill of the Areopagus and on the west by the hill known as the Agoraios Kolonos, also called Market Hill. The Agora's initial use was for a commercial, assembly, or residential gathering place.

The Monument of the Eponymous Heroes, located in the Ancient Agora of Athens, Greece and adjacently situated near the Metroon (old Bouleuterion), was a marble podium that bore the bronze statues of the ten heroes representing the tribes of Athens. Being an important information center for the ancient Athenians, it was used as a monument where proposed legislation, decrees and announcements were posted.

The Temple of Apollo Patroos (meaning "from the fathers") is a small ruined temple of Ionic order built in 340–320 BCE. It is 10 m wide and 16.5 m long, and is located north-west of the Ancient Agora of Athens, near the Stoa of Zeus.Apollo was considered to be the founder of the Ionian race and protector of families. The temple's interior had a cult statue dedicated to the god and made by the famous Greek sculptor Euphranor.Pausanias described the temple in the second century: Euphranor also wrought the Apollon surnamed Patroios (Paternal) in the temple hard by [the Painted Portico oin the marketplace of Athens]. And in front of the temple is one Apollon made by Leokhares; the other Apollo, called Alexikakos (Averter of evil), was made by Kalamis. They say that the god received this name because by an oracle from Delphoi he stayed the pestilence which afflicted the Athenians at the time of the Peloponnesian War.If still in use by the 4th-century, the temple would have been closed during the persecution of pagans in the late Roman Empire, when the Christian Emperors issued edicts prohibiting all non-Christian worship and sanctuaries.

The Stoa of Zeus at Athens, was a two-aisled stoa located in the northwest corner of the Ancient Agora of Athens. It was built c. 425 BC–410 BC for religious purposes in dedication to Zeus by the Eleutherios ("pertaining to freedom"): a cult founded after the Persian War. Stoas were not commonly used for religious purposes, but were typically built for promenades and meetings.It is different from others in that it was a stoa rather than a temple (the common building used for religious purposes). Scholars believe the building also served other civic purposes due to its central location. Researchers think the structure may have been built by Mnesikles, the architect who built the Propylaia. The Propylaia was the Periclean gateway to the Acropolis. In the late first century BC a two-room annex was added, possibly for the cult of the Roman imperial family. The building in all was 43.56 meters by 10.73 meters.

Stoa Basileios (Greek: στοά βασίλειος or τοῦ βασιλέως), meaning Royal Stoa, was a stoa constructed in Ancient Athens in the 6th century BC and substantially altered in the 5th century BC. It was located in the northwest corner (known as "the Herms" because of the great number of Hermae set up there) of the Athenian Agora.The stoa was built in the Doric order and it measures 18 by 7.5 meters. Its facade carries a plain Doric frieze. Its Doric exterior includes 8 columns, while its interior space includes four columns. The modifications of the fifth century BC add two small porches to the archaic structure.The Royal Stoa was the headquarters of the King Archon and of the Areopagos council (in charge of religious affairs and crime). A statue of Themis (representing Justice) stood in front of the building. Copies of some of the city laws were kept in the Stoa.The front of the building was where Socrates met Euthyphro and had the conversation which Plato recreated in his Euthyphro. It was where Socrates was formally charged with impiety by Meletus. Historians believe that the voting for ostracism, a political practice in Athens during the 5th century BC, may have taken place in front of the Royal Stoa.

The Stoa Poikile (Ancient Greek: ἡ ποικίλη στοά, hē poikílē stoá) or Painted Porch, originally called the Porch of Peisianax (ἡ Πεισιανάκτειος στοά, hē Peisianákteios stoá), was erected during the 5th century BC and was located on the north side of the Ancient Agora of Athens. The Stoa Poikile was one of the most famous sites in ancient Athens, owing its fame to the paintings and loot from wars displayed in it.

The Synagogue in the Agora of Athens is an ancient synagogue located in the Ancient Agora of Athens. During an excavation in the summer of 1977, a piece of Pentelic marble apparently once part of a curvilinear frieze over a doorway or niche was discovered a few meters from the northeast corner of the Metroon. The marble fragment is incised with the images of a seven-branched Menorah and a Lulav, or palm branch. The synagogue is thought to date from the period between 267 and 396 CE.
