Legacy The Claude-Decaen street in the 12th arrondissement of Paris pays tribute to him since 1877. A caserne in Caen was named after him (Barracks 43rd Artillery Regiment) but is now gone. The public garden Claude Decaen was laid in the early 2000s on part of the land released by the army. His name is also passed, informally, to the district built on the remains of the military site, called "General Claude Decaen neighborhood."
