Syntagma and Omonia are the main central squares of the town; they are linked by Stadiou Street and Panepistimiou Avenue, along which some of the town’s most beautiful Neoclassical buildings have been erected. Dominating Syntagma Squareis the Greek Parliament building and in front of it the Monument of the Unknown Soldier, guarded by the Evzones in traditional costume. From this square starts the beautiful National Garden (40 acres), south of which stands the impressive Zappeion Mansion (1874-1888). From there you can continue towards the Presidential Mansion (1897) and thence to the Panathenaikon (Kallimarmaro) Stadium, where the first Olympic Games in modern history were held (1896). From there, crossing the Mets neighborhood, the road leads you to the First Cemetery, the oldest one in Athens, basically an outdoor sculpture display with a wealth of wonderful monumental tombstones by some of the most important sculptors of the 19th and 20th centuries.
The Port of Piraeus, as the largest Greek seaport, is one of the largest seaports in Europe and the world, located in the Mediterranean Sea basin. The Port of Piraeus served as the port of Athens since the ancient times. According to Lloyd’s list for top 100 container ports in 2015 Piraeus ranked 8th in Europe and 3rd the Mediterranean Sea. Until the 3rd millennium BC, Piraeus was a rocky island connected to the mainland by a low-lying stretch of land that was flooded with sea water most of the year. It was then that the area was increasingly silted and flooding ceased, thus permanently connecting Piraeus to Attica and forming its ports, the main port of Cantharus and the two smaller of Zea and Munichia. In 493 BC, Themistocles initiated the fortifications of Piraeus and later advised the Athenians to take advantage of its natural harbours’ strategic potential.
