The prominent state of Midea among the Mycenaen centers in Argolida has been stressed from all the researchers of the Mycenaen civilization. Midea was regarded as the third important fortificated Mycenaen acropolis of Argolida, besides Mycenae

The acropolis is built on the top of a conical hill, located in an altitude of 270 m above the sea-level and 170 m above the surounding area. It's found on the middle of the distance between Mycenae and Tirintha and dominates the east feet of the Argolic plain.

The excavations began in 1907 by the German Archaeological Institute and were continued in 1939 by the Swedish archaeologist, who also excavated the site in Dendra, Axel Persson.

The cyclopean wall encloses an area of 24000 m² and protects the upper acropolis. The south-west side of the hill is very steep, which is the reason it remained not walled.

During the latest excavations, areas near the East gate were researched. The East gate was cleared from the landfills. A second internal gate is formed between a Cyclopean wall and the interior side of the fortification.

The skeleton of a girl, with the skull and the spine-cord broken, was found in the area of the East gate hold down by collapsed stones. It must have been one of the victims of the disastrous earthquake which flattened almost everything.

The west side of the acropolis was discovered during the latest excavations. It's formed between the end of the south-west part of the wall, which extends in that part and creates a strong bastion, and a compact wall, which covered s steep rock.

The findings, such as depository pots, millstones, grindstones, stone and leaden vessels, tools made of stone, copper and bones, raw materials and a matrix of steatite to produce jewels, prove that those buildings were warehouses and ateliers.

The recent excavations in the acropolis threw light in the history and importance of the area and proved that Midea composed a significant royal center in Argolida, equivalent to Mycenae and Tirintha.
