Minoan civilization and courtyards between 1650 and 1600 BC. These rocks were likely quarried in Agia Pelagia on the north coast of central Crete. Palaces ("anaktora") are the best-known Minoan building types excavated on Crete. They are monumental buildings with administrative purposes, as evidenced by large archives unearthed by archaeologists. Each palace excavated to date has unique features, but they also share aspects which set them apart from other structures. Palaces are often multi-story, with interior and exterior staircases, lightwells, massive columns, storage areas and courtyards. The first palaces were constructed at the end of the Early Minoan period in the third
Minoan civilization Ancient Egypt). Evans' system divides the Minoan period into three major eras: early (EM), middle (MM) and late (LM). These eras are subdivided—for example, Early Minoan I, II and III (EMI, EMII, EMIII). Another dating system, proposed by Greek archaeologist Nicolas Platon, is based on the development of architectural complexes known as "palaces" at Knossos, Phaistos, Malia and Kato Zakros. Platon divides the Minoan period into pre-, proto-, neo- and post-palatial sub-periods. The relationship between the systems in the table includes approximate calendar dates from Warren and Hankey (1989). The Thera eruption occurred during a mature phase of the LM
