A small part of Orly International Airport lies on the territory of the commune of Athis-Mons, as do several of the hotels that serve the airport.[3]
History
Athis-Mons was formed in 1817 by joining two villages, Athis (along the Seine, and formerly known as Athis-sur-Orge[4]) and Mons (on the adjacent plateau). Nowadays the lower area of the commune is commonly called Athis-Val.
During World War II, a significant portion (approximately 80%) of Athis-Mons was destroyed during the Allied bombing raid of 18 April 1944.[citation needed] Approximately 300 people died and 4,000 people were left homeless.[citation needed] Athis-Mons had to be entirely rebuilt after the war.
