Syntagma square. Athens. Greece. View of Greek Evzones arriving to perform the very slow and highly stylized ceremonial changing of the guard at the monument to the Unknown Soldier in Athens. The monument to the Unknown Soldier, erected in 1929-1932, depicts a relief of a dying Greek solider and is watched around the clock by pairs of Evzones, elite members of the Presidential ceremonial guard unit, standing motionless outside their sentry boxes wearing traditional dress. These guards are wearing the full dress uniform consisting of a white, bell-sleeved shirt and a white foustanella with 400 pleats (Symbolising the 400 years of Ottoman occupation). It is only worn on Sundays or important national holidays.
