ACROPOLIS OF ATHENS
The "Sacred Rock" is the name given to the place where the Acropolis was built. The ancient Greek civilization was represented in an ideal way on the hill and some of the architectural masterpieces were erected on its ground. Over the centuries, the rocky hill was continuously used either as a cult place or as a residential area or both. Inscriptions indicate that the cult to goddess Athena, patron of the city, dates back to the seventh century BC. During the classical period (450-330 BC), important temples were erected on the ruins of the earlier ones:
The Parthenon: built between 447 and 438 BC, it is the most important and characteristic monument of the ancient Greek civilization and its international symbol. Dedicated to Athena Parthenos, it was built in the Doric order and almost exclusively of Pentelic marble. The greatest parts of the sculptural decoration are exhibited in the British Museum since the beginning f the 19th Century.
The Erechtheion: was built in 420 BC in the Ionic order. It was a prostasis on the east side, a monumental propylon on the north and the famous porch of Caryatids on the south. The main temple was divided into two sections dedicated to the worship of the two principal gods of Attica: Athena and Poseidon-Erechtheus.
The Temple of Athena Nike: was built in Ionic order around 420 BC with a row of four columns in front of each of its narrow sides. Some parts of its walls depicts the conference of gods and scenes from battles. The Temple was dedicated to the Nikae (victories) of the goddess patron of the city.
The Propylaea: built between 437-432 BC, it was the monumental gateway to the Acropolis. It constitutes of a central building and two lateral wings most of them with rows of columns of Doric and Ionic orders.

AGORA OF ATHENS (ANCIENT AGORA)
It was used as a residential and burial area in the late Neolithic period (3000 BC) and became a public area in the sixth century BC. It reached its final rectangular form in the second century BC. The Agora was the heart of ancient Athens, the focus of political, commercial, administrative and social activity; the religious and cultural center and the seat of justice. The ancient Agora of Athens had suffered serious damages by the Persians (480/79 BC), Romans (89 BC) and by the Herulae (267 CE) and then gradually abandoned after the Slavic invasion (580 CE). The most important monuments of the Ancient Agora of Athens are:
The Temple of Hephaistos: built around 449 BC in a Doric order, crowning the hill of Kolonos Agoraios. It is known as the "Theseion" and was dedicated to the gods Hephaistos and Athena whose bronze cult statues stood in the interior.
