The Battle of Plataea was a major event of antiquity and according to European academics, it saved Greek and European civilization.

The historic battlefield has been declared an archaeological site. In the archaeological site of Plataea, one of the most interesting visible remains of the present site is the fortification enclosure of the ancient city, with total length of about 4.5 kilometers of various periods of time, mainly from the 5th century BC – 4th century AD, however, few remains of prehistoric walls are preserved. The enclosures have square towers at intervals.

With the chisel of Praxitelis

Northwest of the fortified acropolis is the Doric temple of Hera. Inside it was the statue of Hera, the work of the sculptor Praxitelis.

To the northwest of Heraion, the Xenonas(guesthouse) or Katagogionwas built to accommodate the pilgrims of Heraion. It was quadrilateral with many rooms spread over the two floors of each side and an internal central courtyard. Only one corner and one side of this great building survives today.

Stone foundations were attributed to the altar built by the Greeks, at the request of the Delphic Oracle, after the victorious battle of Plataea to honour Eleftherios Zeus who gave them victory. The altar was central part of the annual celebration of the “Eleutherians”. Near the altar of Eleftherios Zeus, a tomb with slabs was excavated, containing many skeletons and no grave offerings. It was thought to be the “common monument” of the Greeks who died in the battle of 479 BC.

Throughout the area enclosed by the fortification enclosure there are remains from at least the 6th – 15th century AD that were partly built with ancient material.
