I was a student in Rennes in the Breton department when they closed the Welsh course (I was following the Modern Irish course) but there was nothing about medieval Celtic languages appart a general course by H.Bihan, but nothing about teaching the actual languages.
There is an introduction course to Old Irish in Brest, in the master L3C taught by Anna Matheson who is actually attached to the University of Tours:

Sadly, expertise in languages (old and present) is eroding at high speed in France :(
