In 2021 Ferronnerie d'Art Française completely restored the grilles of the communion bench of the Prytanée Militaire de la Flèche. A lot of work to restore the embossed sheet iron ornaments on this authentic grille from the end of the 17th century was carried out to the highest standards. Gilding with 24ct gold leaf was carried out on the ornamentation, according to the results of stratigraphies carried out during the preparation of the restoration.
