In the late 1920s, architects E. Lazaridis and E. Dimitriades Rok designed the Monument of the Unknown Soldier. The relief figure on the marble tomb was sculpted by famed artist, Konstantinos Dimitriades. During the initial phases of its construction, prior to its final placement, extensive excavation was undertaken in front of the Parliament building, lowering the ground level by approximately 6 metres, to the level of Amalias avenue.
Heavily influenced by the archaic art style, the monument is strictly minimalist in design, its only modernist decorative elements being the bronze shields. The monument is guarded day and night by the Presidential Guard of Evzones, and is where officials dedicate wreaths in honour of the Unknown Soldier.
