Syntagma Square, Central public square in Athens, Greece

Syntagma Square is a broad paved square in central Athens, bordered by Amalias Avenue to the east, Otto Street to the south and King George I Street to the north. Its eastern side is higher than the western, reached by a marble staircase under which the metro station lies. Two green areas with shade trees stand to the north and south, and a mid-19th-century fountain sits in the centre.

The area was called Perivolakia on the city's edge until 1834, when Athens became the capital and the square was laid out as Palace Square. In September 1843 soldiers under Colonel Dimitrios Kallergis gathered before the palace and forced King Otto to grant a constitution, and the square was renamed Syntagma. Its layout was completed in the early 1850s.

The ceremonial guards at the Tomb of the Unknown Soldier wear traditional uniforms and perform synchronized movements that reflect Greek military heritage. Visitors can watch this ritual throughout the day, making it a focal point for understanding modern Greek national identity.

The square is easily reached by metro lines and bus connections, serving as a major transportation hub for the city. Visitors should be prepared for the uneven terrain with multiple levels and steps that connect different sections.

Before the National Garden existed, Syntagma Square was considered Athens' only park. In its early layout the centre held a goldfish pond, a large four-sided clock and an octagonal marble platform where the Guard band played every Thursday and Sunday.
