Syntagma Square (Greek: Πλατεία Συντάγματος, pronounced [plaˈtia sinˈdaɣmatos], "Constitution Square") is the central square of Athens.[1] 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.[2] 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 (Greek: Σύνταγμα) alone also refers to the neighbourhood surrounding the square.
