The first organised settlement to be established in the area of
dates to the Middle Minoan period (19th century BC). The site is mentioned as a-mi-mi-so in the Linear B tablets.
Habitation continues until the end of the Mycenaean period (12th century BC). In the Archaic period (7th century BC) a sanctuary
dedicated to Zeus Thenatas is founded and remaines in use until the 2nd century AD. After a long period of abandonment, the
site was again inhabited during the Venetian era. This medieval settlement, called Mesovouni, was located on the hill of Palaiochora
and was destroyed in the first years of the Turkish occupation.
The site was excavated by Spyridon Marinatos in 1929-1938 and then by Stylianos Alexiou. In 1983-85 the architectural
remains were cleared and drawn by the Archaeological Institute of the University of Heidelberg. Consolidation and conservation works
are carried out at intervals by the 23rd Ephorate of Prehistoric and Classical Antiquities.
The most important monuments of the site are: The "Villa of the Lilies".
