As one leaves the crypt on the left (the south side), halfway up the staircase, several meters up, you can make out a trace of a fresco showing St. Quentin. Wall paintings of this kind once almost entirely covered the walls of the building. There are also slight traces of painted motifs on the columns at the entrance of the choir. Unfortunately, the frescos disappeared after the fires in earlier centuries, and what was left of the paint peeled off or was damaged by humidity.
As you go down the southern aisle, you see, set in the wall, the tombstone of a Father Abbot, which was found in village houses broken in two pieces and then reassembled and put back in its original place in the church.
On the same wall, hangs a small statue of St. Vincent, patron saint of wine growers. It reminds us of the rich past of wine production in the area of Mont-Devant-Sassey. Before phyloxera, a diseasethat attacked vineyards everywhere at the beginning of the 20th century, the hills where the church stands were covered with grapevines. There is proof of this when you look at the old postcards displayed in the case at the entry to the church.
