Athens is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning around 3,400 years. Classical Athens, as a landlocked location was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus.
The Acropolis, a Unesco World Heritage Site, was the ancient fortified town of Athens, dating back to the Late Bronze Age, and the site of the best buildings of the Greek Classical age: the Parthenon, the Erectheion, the Temple of Athena Nike. Acropolis dominates the Athenian sky and symbolizes the foundation of modern culture and civilization.
The Ancient Agora: The site of the Ancient Agora in a very green space and a very beautiful view of the Acropolis. You will see the Temple of Hephaestus, the best preserved ancient Greek temple, the Attalos Stoa, the museum of the agora which is a reconstructed ancient building.
Syntagma Square: Check out the Parliament building and the newly-restored Grande Bretagne Hotel. Also, catch the changing of the guards in front of the Parliament every hour on the hour. Their uniforms and walking style is fun to see but make sure you don't stand on the wrong side of them if you want to take a picture.
The Kerameikos: The site of the ancient cemetery of Athens. It also houses the Dipylon Gate, where the Panathenaic procession would begin. It has a museum showcasing many of the grave stele and other archaeological items found on the grounds.
The Temple of Olympian Zeus: Only the ruins remain today. The column that has fallen and can still be seen on pieces was brought down during a thunderstorm about a century ago. The 1896 Olympic Stadium and Hadrian's Arch are located nearby.
