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 eruption activity and the possible generation of tsunamis. Man-made structures not buried during Minoan A were completely destroyed. The third phase was also characterized by the initiation of caldera collapse. The fourth, and last, major phase (BO/Minoan D) was marked by varied activity: lithic-rich base surge deposits, lahars, debris flows, and co-ignimbrite ash-fall deposits. This phase was characterized by the completion of caldera collapse, which produced megatsunamis. Although the fracturing process is not yet known, the altitudinal statistical analysis indicates that the caldera had formed just before the eruption. The area of the island was smaller, and the southern and eastern
