Aizy-Jouy is some 15 km north-east of Soissons and 20 km south-east of Laon. National Highway N2 from Soissons to Laon passes just north of the commune. The commune can be accessed by Highway D14 running south from the N2 continuing through the heart of the commune and the town continuing south to Vailly-sur-Aisne. Highway D15 branches from the D14 at the southern border of the commune and heads north-east through the eastern part of the commune and then to Pargny-Filain. There are also several small country roads criss-crossing the commune and exiting on all sides of the commune. There are no villages or hamlets in the commune other than Aizy-Jouy.[3]
A stream rises from ponds north of the town and flows south through the commune joining with other streams rising in the north-east of the commune and flowing south to the river Aisne. The commune has a substantial amount of forest mostly following the course of the streams with the rest of commune (about 30%) farmland.[3]
Before 1971 the communes of Aizy and Jouy were separate and their population was counted separately. In 1954,[5] Aizy had 242 inhabitants and Jouy 140.
The Quarry Carvings (1917)[21] The Creute du Caid operated for a century and a half and was occupied by the belligerents during the First World War. They left some cave carvings - some of which are of high quality.[22]
