Sesklo (Σέσκλο; Seshklu) is a village in Greece that is located near Volos, a city located within the municipality of Aisonia. The municipality is located within the regional unit of Magnesia that is located within the administrative region of Thessaly. During the prehistory of Southeastern Europe, Sesklo was a significant settlement of Neolithic Greece, before the advent of the Bronze Age and millennia before the Mycenaean period.
The settlement at Sesklo gives its name to the earliest known Neolithic culture of Europe, which inhabited Thessaly and parts of Macedonia. The Neolithic settlement was discovered in the 19th century and the first excavations were made by the Greek archaeologist Christos Tsountas.
The oldest fragments researched at Sesklo place development of the culture as far back as c. 7510 BC — c. 6190 BC, known as proto-Sesklo and pre-Sesklo. They show an advanced agriculture and a very early use of pottery that rivals in age those documented in the near east.
Available data also indicates that domestication of cattle occurred at Argissa as early as c. 6300 BC, during the Pre-Pottery Neolithic. The aceramic levels at Sesklo also contained bone fragments of domesticated cattle. The earliest similar occurrence documented in the Near East is at Çatalhöyük, in stratum VI, dating c. 5750 BC, although it might have been present in stratum XII too — c. 6100 BC.
The Neolithic settlement of Sesklo covered an area of approximately 20 hectares during its peak period at c. 5000 BC and comprised about 500 to 800 houses with a population estimated potentially, to be as large as 5,000 people.
The people of Sesklo built their villages on hillsides near fertile valleys, where they grew wheat and barley. They kept herds of mainly sheep and goats, although they also had cattle, swine, and dogs.
Their houses were small, with one or two rooms, built of wood or mudbrick in the early period. Construction techniques later became more homogeneous and all homes were built of adobe with stone foundations.
