The municipality of Marousi (72,333 inhabitants in 2001, 1,264 ha) is a northeastern suburbs of Athens. The Athens Olympic Sports Complex, the largest sports complex in Greece, is located in Marousi.
Marousi dates back to the era of the ancient Athenian Republic; its ancient name was Athmonon, and it represented one of the 10 Athenian sub-cities. The area held a main ancient temple, where Amarysia Artemis, the goddess of hunting, was adored, and the town modern name (Amaroussi) derives from that of the goddess, Amarysia.
The municipality was not changed with the 2011 local government reform. Olivier Touzeau, 1 March 2013
