In classical Greece Hippeios Colonus (Greek: Ίππειος Κολωνός, Colonus of the Horses) was a deme about 1 km (1 mile) to the northwest of Athens, near Plato's Academy. There is also the "Agoraios Kolonos" (Αγοραίος Κολωνός, Colonus of the Agora), a hillock by the Athens Agora on which the temple of Hephaestus still stands.

Hippeios Colonus held a temple of Poseidon and a sacred grove to the Eumenides.

Oedipus was buried there, and Sophocles who was born there, described it in his Oedipus at Colonus.

Today its modern name is Kolonos and it is a densely populated working-class district of the Municipality of Athens.

The subdivision is passed by Lenorman Avenue and streets runs almost diagonally. Konstantinopouleos Avenue and the OSE is to the southeast. The nearest train station is at the Larissa station . In 1992, Athinon Avenue was closed for a construction of an overpass to avoid traffic congestion with railway crossings. The road was detoured with Lenorman Avenue until 1993 when the overpass was first opened. The overpass only has an eastbound off-ramp and a westbound on-ramp.
