In 473 bc under the weight of the oncoming collision between Greeks and Persians, the scale of the threat created frictions that had as a result the efforts of creating a unified coalition between Greeks. The first clash of this war happened at Thermopylae, with Leonidas as the leader of the Greek army against the Persian army and Xerxes. 

 The battle lasted three days, it however echoed throughout Greece and Persia, succeeding at creating an incision in the collective memory of both nations, taking its place as one of the most remarkable battles in history.

 This thesis undergoes the creation of a museum, following along the events of the battle, presenting archaeological findings with the aim of thoroughly informing its standpoint as well as the culture of the opposing sides.

 Located in the cite of The Center for Historical Information of Thermopylae  having expanded its north and east ends, the goal of the museum is to function as a landmark - pole of attraction and contribute to the further development of the region that stands neglected and its attendance so that she can stand worthy and to narrate in the best way the history that lies there and highlight an important historical event of Greek history.

 In a region that stands largely unexcavated in great extend and to the radical change of its landscape thanks to the embankments of Spercheios river, the museum stands between the ancient pass and modern shoreline, alternating the concept of extroversion and introversion in order to restore again the premise that enabled the successful defence of the Greeks, reducing the numerical advantage of the enemy, transforming it into a battle of quality.
