Arcature (gallery ©)

The translation in the title is followed by this sign ©; this means that it has been "invented" by me.

Arcatures can be aveugles (blind) as well as ajourées (ajoure) or ouvertes (open), such as this claire-voie (window gallery) in 25 Rue de la République in Cluny.
Arcatures are often small and decorative.
