We take the Metro to Syntagma Square. The impressive building of the Greek parliament is here. The history of the impressive building of the Hellenic Parliament is intimately linked to the history of the Modern Greek state. Initially, the building served as the palace of Kings Otto and George I. It became the Parliament and Senate building a hundred years after it was constructed and still houses the Hellenic Parliament today. Through all those years, the building has undergone a series of changes and has been modernized. Every hour the Change of the Guards takes place in front of the building by the Evzones, a special unit of the Hellenic Army, also known as Tsoliades, that guard the Monument of the Unknown Soldier in front of the Hellenic Parliament and the Presidential Mansion. Through the historical movement of Greece, the Evzones have become symbols of bravery and courage for the Greek people. The duties of the soldiers are part of a ceremonial nature. Every soldier guards for about an hour, 3 times in total every 48 hours. Throughout these 60 minutes, they have to stand perfectly still until it is time to switch to another guard. During the changing, they work in pairs so they can perfectly coordinate their moves. The steps that the official ceremony requires at the time of changing are carried out slowly to protect their blood circulation after 60 min of immobility. The soldiers of the Presidential Guard are selected according to their height, excellent physical condition, and psychological state as well as character and morality, as they follow hard training before they become part of this honorary unit. The training lasts for one month and includes exercises to keep the body and mind still. Apart from staying still, the soldiers must also not make any face or eye move and must not show any expression.
