Syntagma Square is named after the Greek constitution syntagma that was proclaimed from the balcony of the royal palace that overlooks the square on 3 September 1843. The former palace has housed the Greek parliament since 1935.
Syntagma Square is a good point from which to begin your orientation in the city - its also much better in appearance than it used to be even a few years ago: the manic Athenian traffic has been re-routed and a concerted effort at beautification has been in place - with some good results. Points of convenience include numerous cafes, restaurants and all the usual fast food outlets, a new metro stop, a host of airline offices, etcetera.
The square serves as an occasional rallying place for demonstrations and public celebrations.
