Anavyssos, 15km south of Kalyvia, is the historic continuity of the ancient municipality of Anaflystos. A place that embraces the sea of the Saronic Gulf and the inland of Lavreotiki. During the geometric period, significant vessels were made in Anavyssos, and during the Archaic period imposing and robust Kouros statues were created there and survived through the centuries; the greatest of them was Kroisos, also known as Kouros of Anavyssos, which you can admire today in the magical Kouros room at the National Archaeological Museum of Athens.

From deep inside the grounds of Anavyssos (Ari site) argentiferous lead (silver) was mined, which Athens used for the production of coins during classical years. The prehistoric settlements in Agios Nikolaos and on Artsinta islet are the first evidence of the existence of human activity in Anavyssos. In Roman times, the existence of an aqueduct at the area of Olympos, the cemetery in Agios Nikolaos as well as other contemporary findings within the town’s residential area, record an intense human activity through time.

The operation of the famous Salt Lake area was a continuous process of salt harvesting during contemporary years. A process that would come to be, in the early 20th century, the main form of employment of refugees that settled in the area after they fled their homelands in Asia Minor and Anatolia. The seafront of Anavyssos, attracts, even today, sea lovers and water sports enthusiasts, along its miles of coastline. Viticulture, olive trees, fishing and tourism are now the main sources of local development in Anavyssos. The wetland of Agios Nikolaos, is certainly one of the most unique ecosystems of the Municipality of Saronikos, its peculiar “tombolo”, a mound, creating a very particular land form. Today, the total population of Anavyssos amounts to 6,200 residents
