(building executed to an aesthetically considered design) was extinct in Greece from the end of the Mycenaean period (about 1200 BC) until the 7th century, when urban life and prosperity recovered to a point where public building could be undertaken. But since most Greek buildings in the Archaic and Early Classical periods were made of wood or mud-brick, nothing remains of them except a few ground-plans, and there are almost no written sources on early architecture or descriptions of buildings. Most of our knowledge of Greek architecture comes from the few surviving buildings of the Classical, Hellenistic and Roman periods (since Roman architecture heavily copied Greek), and from late written sources such as Vitruvius (1st century AD). This means that there is a strong bias towards temples, the only buildings which survive in any number.
The standard format of Greek public buildings is well known from surviving examples such as the Parthenon, and even more so from Roman buildings built partly on the Greek model, such as the Pantheon in Rome. The building was usually either a cube or a rectangle made from limestone, of which Greece has an abundance, and which was cut into large blocks and dressed. Marble was an expensive building material in Greece: high quality marble came only from Mt Pentelus in Attica and from a few islands such as Paros, and its transportation in large blocks was difficult. It was used mainly for sculptural decoration, not structurally, except in the very grandest buildings of the Classical period such as the Parthenon.
There were two main styles (or "orders") of Greek architecture, the Doric and the Ionic. These names were used by the Greeks themselves, and reflected their belief that the styles descended from the Dorian and Ionian Greeks of the Dark Ages, but this is unlikely to be true. The Doric style was used in mainland Greece and spread from there to the Greek colonies in Italy. The Ionic style was used in the cities of Ionia (now the west coast of Turkey) and some of the Aegean islands. The Doric style was more formal and austere, the Ionic more relaxed and decorative. The more ornate Corinthian style was a later development of the Ionic. These styles are best known through the three orders of column capitals, but there are differences in most points of design and decoration between the orders. See the separate article on Classical orders.
Most of the best known surviving Greek buildings, such as the Parthenon and the Temple of Hephaestus in Athens, are Doric. The Erechtheum, next to the Parthenon, however, is Ionic. The Ionic order became dominant in the Hellenistic period, since its more decorative style suited the aesthetic of the period better than the more restrained Doric. Some of the best surviving Hellenistic buildings, such as the Library of Celsus, can be seen in Turkey, at cities such as Ephesus and Pergamum. But in the greatest of Hellenistic cities, Alexandria in Egypt, almost nothing survives.
