Omonoia Square or Omonia Square (Greek: Πλατεία Ομόνιας Plateia Omonoias or Platia Omonias) is a square in Athens. It contains a train station used by the Athens Metro and the Ilektrikos, appropriately named Omonoia Station. The square with 3 Septemvriou almost aligns to the north.

The Square

The circle accesses Tritou September in the north (September 3, entrance/exit), Panepistimiou (former exit), Agiou Konstantinou in the west (formerly entrance/exit, now exit), Panagis Tsaldaris which accesses with Peiraios (entrance/exit, now exit), Athinas (entrance/exit) in the south which is now a waklway and Stadio (named after the ancient Stadium) in the southeast (exit) once continued the circle.

The traffic circulation from the 19th century up until 1998 used to be fully around with six streets of which five were entrances and exits and later had six traffic lights. In the 19th century to the 1950s, the shape was almost like a square having sidewalks by the edge and in the square, surrounded by neoclassical buildings that have no more than three-stories high, most of them were nearly two-stories. It only had three lanes, the right lanes were tracks for the old tram buses, the middle of the square featured several beautiful palm trees which were smaller before the Balkan Wars that were cut down in the 1950s and the fountain in the middle which was the last object standing until 2000. Cannons were aligning in the circle during the Balkan Wars. After the wars in Greece, the square including its trees were demolished except for the fountain to make room for traffic. The shape became blue with a pentagon facing northwest and a green hexagon that was mainly grass facing to the northeast and a circle in the middle. The road was later repaired along with the sidewalks which were partially demolished and later, the road was repaved in a shape of a circle totaling four lanes and part of the former road transformed into a larger sidewalk, traffic lights were later installed and half neoclassical buildings were demolished in the western and the northern parts transforming into a few-story towers, neoclassical buildings remain in the northern part and within Athinas Street. The remaining trees were in the northern portion which were planted in the 1950s and remain to this day.

The old circle featured a fountain in a middle and a train station was nearby but was rebuilt. Trees were later replanted again within Omonoia and encircles the fountain once again and two more on what were pavement. When the part of the square were shut down for renovations for the Athens 2004 Summer Olympics along with the station which became sidewalks and the west and the east sides were eliminated for good and reduce traffic to the westbound lanes for the upper part and the eastbound lanes at the south leaving one example no access to Peiraios to Tritou Septembriou. The square has been existed since the ancient times, the square later became abandoned but later revived when Athens became a city again. Several television shows filmed Omonoia.

When Greece won the Eurobasket 2005 finals and became the 2005 Eurobasket Champion, crowds of people participated within Omonoia Square and around celebrating the victory and lasted throughout the night. Other victories of Greece were also celebrated throughout the century at Omonoia.
