It was during maintenance work undertaken in 1979 in the Church of St Paterne in Montrond that the wall paintings were discovered, hidden under a thick plaster cover and masked by a large altarpiece of the classical period, which was reinstalled at the back of the church. It should also be noted that during this restoration work, a set of “acoustic pots” were discovered in the walls of the choir, as exists in many churches in our region and whose use, it seems, dates back to the Gallo-roman. Finally, in the late 1990s, it was decided to replace the windows with stained glass.
