The Presidential Guard is a ceremonial infantry unit that guards the Tomb of the Unknown Soldier and the Presidential Mansion in Athens, Greece. The unit is distinguished as the last unit of Evzones in the Hellenic Army, and is closely associated with the traditional Evzone's uniform, which evolved from the clothes worn by the klephts in the Greek War of Independence. The most visible item of this uniform is the fustanella, a kilt-like garment. In 1868–1914 and 1937–1973, the guard also included a cavalry company.

Syntagma Square is the central square of Athens, Greece. The square is named after the Constitution that Otto, the first King of Greece, was obliged to grant after a popular and military uprising on 3 September 1843. It is located in front of the 19th-century Old Royal Palace, housing the Greek Parliament since 1934. Syntagma Square is the most important square of modern Athens from both a historical and social point of view, at the heart of commercial activity and Greek politics. The name Syntagma alone also refers to the neighbourhood surrounding the square. The metro station underneath the square, where lines 2 and 3 connect, along with the tram terminal and the numerous bus stops, constitutes one of the busiest transport hubs in the country.
