About our logo : what is ADETTE and why 91 ?
  • ADETTE is an association of people that want to promote this department.
  • 91 is the department's number. You can see it in the post code of each town and on car number plates.

Usually, the department number depends on its order in the alphabet (for example 01 for "Ain", 02 "Aisne", and so on...) but Essonne was created in 1964 by the splitting of "Seine et Oise", a big department, into 5 new ones. The last number was 90 "Territoire de Belfort", so we chose 91 "Essonne", 92 "Hauts de Seine"... .
