Ancient Diocese of Alais

The former French Catholic diocese of Alais (now written Alès, and in Latin: Alesiensis) was created in 1694, out of territory previously part of the diocese of Nîmes. It was suppressed after the French Revolution, with its territory being divided between the diocese of Avignon and the diocese of Mende. Its seat was Alès Cathedral.

This is not the diocese of Ales-Terralba in Italy, nor the Ancient Diocese of Alet in south-west France
