Chalandri older form Chalandrion and in Ancient Greek Flya or Halandri is a northern suburb in Athens, Greece, and a municipality of the Attica region. It is the birthplace of Euripides.
Chalandri is a suburb in Northern Athens, around 12 km from the centre; its location corresponds with one of the 10 ancient Dimoi (boroughs) of Athens, known as Flya (Greek: Φλύα). Chalandri was a small village in Attica until the rapid expansion of Athens and of the village during the 1960s and 1970s made the two meet; the border with Athens is now indistinguishable. The area, nevertheless, remains relatively sparsely populated, and has one of the highest ratio of open green areas per citizen in Athens. Several embassies are based in Chalandri.
