Piraeus, Greece

Piraeus is a port city within the Athens urban area in the Attica region of Greece. The port of Piraeus is the chief port in Greece, and among five biggest passanger port in Europe, serving about 20 million passengers annually. Piraeus is among the busiest ten ports in Europe in terms of container traffic, and is the busiest container port in the Eastern Mediterranean. The University of Piraeus is one of the largest universities in Greece, and includes the country's second-oldest business school, as well as the oldest academic department dedicated to the study of finance.

  • Has approx.135,861m2 of green area
  • Unemployment rate 19,62%
  • Households with children: 88%


The major environmental challenges are lack of open green spaces (approx. 0.83 m2 /person) and parks, the high-density buildings, as well as narrow streets with small pedestrian free space (warmed-up by air conditioners’ hot air exhaust), high level of air pollution (due to the ships emissions). There is not enough shading for protection of pedestrians against direct solar radiation and other UHI effects in summer, which, as deterrent, severely reduces the number of visitors to the site in summer, thus WB of the local population. Marine aquatic environment close to the water promenade is “in the need of improvement” for both aesthetic and environmental conditions. The riverine inland area (Akti Dilaveri), although directly connected to the promenade, is underdeveloped with poor quality water. The social cohesion has been affected from high unemployment rate, increased economically non-active population, lack of business opportunities.

Piraeus was a complete town as early as the 6th century BC, owing largely to the brains of noted statesmen Themistocles and Pericles. They built the so-called defensive Long Walls, protecting the road to Athens and securing the port. Of note, early Piraeus was then referred to as Greece's Emporion.

Hippodamus, son of Euryphon, a native of Miletus, invented the art of planning and laid out the street plan of Piraeus“ Aristotle.

An element of uniqueness of the Piraeus is Rebetiko song, which has recently been included in the UNESCO list of intangible cultural heritage monuments. The history of rebetiko in Piraeus, dates back to 1920, where slowly grew in number and helped to create a vibrant popular culture. Also World-famous musician George Dalaras is Piraeus-born.
