Every Sunday morning at 11 am, people gather in Syntagma Square to watch the official changing of the guards, the military unit whose members stand proudly in perfect stillness in front of the Hellenic Parliament. There are of course changing every hour in the day, but on Sundays, it is the official ceremony with the official customs.
The Evzones is a special unit of the Hellenic Army, also known as Tsoliades, who 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 Presidential Guard, as the unit is now called, was constituted in 1868 and has taken many names through centuries (Guard of the Flag, Royal Guard, etc).
