Historically the Evzones were light infantry units in the Greek army, today they are members of the Presidential Guard. They stand guard at both the Presidential Mansion and the Tomb of the Unknown Soldier. I knew that they do changing of the guard ceremonies and I wasn’t particularly interested about going out of my way to see them but after leaving the Panathenaic Stadium I happened to come across one such ceremony outside of the Presidential Mansion.
