Plaza / Square
Syntagma Square is the central square of Athens. 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. — Wikipedia
