The Changing of the Guards in Athens

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.
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 with 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
in really slow motion to protect their blood circulation after 60 min of immobility.
