Syntagma Square to me is a square with benches around the outskirts, positioned beneath trees for shade, and has a fountain in it's centre, and a couple of beggars. Unfortunately while I was there the fountain wasn't working most days, and only gave a trickle on one occassion. (I have the proof). There are a few stalls selling beverages, ice creams, souvenirs and tobacco etc., and seems to be the meeting place for many of the locals. To the East however, literally across the road, you find the Evzones of the Presidential Guard at the Tomb of the Unknown Soldier, and beyond that the Parliament Building. To the West, you have the shopping area, and a number of cafes, always worth a visit. There is a taxi rank on the South side of the square. If you follow the main road to the south, you will come across a few places of interest including the Hadrians Arch and the Temple of Zeus, Plaka, the Acropolis museum etc.
