Ancient Greek city, on the Chalcidice Peninsula, northeastern Greece. From the late 5th century BC it was the head of a strong confederacy of Greek towns known as the Chalcidian League. It was destroyed by Philip II in 348 BC. Excavations have revealed the grid plan of the ancient town and provided material for studying the relationship between Classical and Hellenistic Greek art.

Olynthus (Greek: Όλυνθος olunthos, a fig which ripens too early; the area abounded in figs) was an ancient city of Chalcidice, built mostly on two flat-topped hills 30–40m in height, in a fertile plain at the head of the Gulf of Torone, near the neck of the peninsula of Pallene, about 2.5 kilometers from the sea, and about 60 stadia (c. 9–10 kilometers) from Poteidaea.
Olynthus became a Greek polis, but it remained insignificant (in the quota-lists of the Delian League it appears as paying on the average 2 talents, as compared with 6 to 15 paid by Scione, 6 to 15 by Mende, 6 to 12 by Toroni), and 3 to 6 by Sermylia from 454 to 432 .
In 432 King Perdiccas II of Macedon encouraged several nearby coastal towns to disband and remove their population to Olynthus, preparatory to a revolt to be led by Potidaea against Athens (Thuc. 1.58). This synoecism (συνοικισμός) was effected, though against Perdiccas's wishes the contributing cities were preserved. This increase in population led to the settlement of the North Hill, which was developed on a grid plan. A 423 Olynthus became the head of a formal Chalcidic League, occasioned by the synoecism or by the beginning of the Peloponnesian War and fear of Athenian attack. During the Peloponnesian war it formed a base for Brasidas in his expedition of 424 and refuge for the citizens of Mende and Poteidaea that had rebelled against the Athenians (Thu. ii, 70).
After the end of the Peloponnesian War the development of the league was rapid and ended consisting of 32 cities. About 393 we find it concluding an important treaty with Amyntas III of Macedon (the father of Philip II), and by 382 it had absorbed most of the Greek cities west of the Strymon, and had even got possession of Pella, the chief city in Macedon. (Xenophon, Hell. V. 2, 12).
In this year Sparta was induced by an embassy from Acanthus and Apollonia, which anticipated conquest by the league, to send an expedition against Olynthus. After three years of indecisive warfare Olynthus consented to dissolve the confederacy (379). It is clear, however, that the dissolution was little more than formal, as the Chalcidians (Χαλκιδῆς ἀπò Θρᾴκης) appear, only a year or two later, among the members of the Athenian naval confederacy of 378-377. Twenty years later, in the reign of Philip, the power of Olynthus is asserted by Demosthenes to have been much greater than before the Spartan expedition. The town itself at this period is spoken of as a city of the first rank (πóλις μuρἰανδρος), and the league included thirty-two cities.
When the Social War broke out between Athens and its allies (357), Olynthus was at first in alliance with Philip. Subsequently, in alarm at the growth of his power, it concluded an alliance with Athens. Olynthus made three embassies to Athens, the occasions of Demosthenes's three Olynthiac Orations. On the third, the Athenians sent soldiers from among its citizens. After Philip had deprived Olynthus of the rest of the League, by force and by the treachery of sympathetic factions, he besieged Olynthus in 348. The siege was short; he bought Olynthus's two principal citizens, Euthycrates and Lasthenes, who betrayed the city to him. He then looted and razed the city and sold its population—including the Athenian garrison—into slavery. According to the latest researches only a small area of the North Hill was ever re-occupied, up to 318, before Cassander forced the population to move in his new city of Kassandreia.
Though the city was extinguished, through subsequent centuries there would be men scattered through the Hellenistic world who called them Olynthians.
The city of Olynthus lies in the hill named Megale Toumba near the village of Myriophyto. The probable site of Olynthus was identified as early as 1902. Between 1914 and 1916 plans were made for an excavation by the British School at Athens, but these fell through.
The ancient city extends in two hills that detach from a small coulee and possess an area with 1500 m long and 400 m in width. Excavations began in 1928. Prof. D. M. Robinson of Johns Hopkins, under the American School for Classical Studies at Athens, conducted four seasons of work: in 1928, 1931, 1934, and 1939. The results of the excavations were digested into fourteen folio volumes. The excavation had uncovered more than five hectares of Olynthus and a portion of Mecyberna (the harbor of Olynthus). On the North Hill this hurried pace proved relatively harmless due to the simple stratigraphy of an area of the city occupied only for 84 years and subjected to a sudden, final destruction; but the data from the South Hill was badly muddled. Nonetheless the work was excellent for its time, and remains supremely valuable. Much of the stratigraphy of the North Hill has been reconstructed by Nicholas Cahill. The site is now in the charge of Dr. Julia Vokotopoulou, and the XVI Ephorate of Classical Antiquities.
The neolithic settlement is located in the edge of the southern hill and was dated in the 3rd millennium BC. The houses were built by stone blocks and had one or two rooms. The pottery that was found was the typical of that period comprising monochrome ceramic vases. The end of this rural settlement was abrupt and is placed around the first millennium.
The archaic city was built under a provincially urban planning and extended throughout the whole south hill. Two avenues were revealed along the eastern and western edges of the hill that communicated inter se with crossing streets. Along the south avenue shops and small houses were found while the administrative part was located in the north part of the hill, where the agora and a deanery were found.
The classical city was established on the must larger north hill and to its western slope. The excavations, which cover only the 1/10 of the city's total area, have revealed a Hippodamian grid plan. Two large avenues were discovered, with an amplitude of 7 meters, along with vertical and horizontal streets that divided the urban area into city blocks. Each one had ten houses with two floors and a paved yard. Very important for the archaeological research are considered the rich villas that were excavated in the aristocratic suburb of the city located in the eastern part of the north hill since there was found some of the earliest floor mosaics in Greek art.
Both the archaic and classical city were protected by an extended land wall. Parts of the foundations of the wall were revealed in the north hill and elsewhere, but they are not enlightening on which method was followed for their construction. Archaeologists suppose that it was built with sun-dried bricks with a stone base, but it's difficult to tell since the city was literally leveled by Phillip.
As it concerns the public buildings, the Agora is placed in the south edge of the north hill, near the eastern gate, along with a public fountain, an arsenal and the city's parliament building (Βουλευτήριον).
There is a small museum featuring artifacts recovered from Olynthus, and the whole archaeological site is open to public tours during daylight hours.
