Syntagma Square for the Tomb of the Unknown Soldier Greece, which is located at the Parliament Building. Every hour, guards called Evzones perform the Tomb of the Unknown Soldier Greece changing of the guard. The Evzones wear curious uniforms with pom-poms on the toes of their shoes and skirts with stockings. The uniforms differ in the summer from the winter garb, and on Sundays and special celebrations the uniform is the most formal. The 11 o'clock a.m. Sunday changing of the guards at the Tomb of the Unknown Soldier Greece is a more ornate ceremony, where scores of people gather to watch.
