Polatlı (formerly Ancient Greek: Γόρδιον, Górdion and Latin: Gordium) is a municipality and district of Ankara Province, Turkey.

Since the mound was being used by local people as a quarry, rescue excavations of its southern and central parts were carried out in 1949 by the Anglo-Turkish expedition led by Seton Lloyd, and Nuri Gökçe, then the director of the ‘Hittite Museum in Ankara’.

On his expedition to the east, Alexander the Great cut the famous Gordian Knot, an omen of his coming rule over the whole Asia.

Polatlı also occupied an important place in the Greco-Turkish War of 1919-1922 as the Battle of Sakarya (August 23-September 13, 1921) was fought here, the utmost eastern point reached by the advancing Greek Army in Anatolia.

The city has a good range of restaurants, bars, schools and other important amenities but still a quiet rural feel to it, and little social life except cafes, patisseries and window shopping on a Sunday afternoon.

[citation needed] There is a military base here and the Turkish Army Artillery School was established in Polatlı in the early 1940s and is still an important institution in the town.
