In the state capital, Athens, members of the elite Evzones light infantry unit, provide a 24-hour honor guard, with an hourly guard change, at the Presidential Mansion and at the Tomb of the Unknown Soldier, off Syntagma Square at the foot of the Hellenic Parliament. The changing of the Guard at the Tomb of the Unknown Soldier in particular has become a tourist attraction, with many people marvelling at the guards, who stand motionless for two 20-minute intervals, during their 1 hour shifts.
