Ofis Publik ar Brezhoneg

One of its missions is to collect and distribute socio-linguistic data, in order to approach language revival with a basis in science and facts.

Its remit is to collect data on the Breton language (Arsellva ar brezhoneg) and publish it, and advise communes on bilingual signage and place names.

(From 1 July 1999 to September 15, 1999, 42 administrations, associations or companies have made an appealed to the national government to allow use of Breton as an official language.)

It was established to replace the Ofis ar Brezhoneg/Office de la langue bretonne, which had been created on 1 May 1999 by the Region of Brittany.

The Observatory of the Breton Language (l'Observatoire de la langue bretonne), led by the deputy director Olier ar Mogn, is located in Rennes.
