The ancient parish chapel, dedicated to the apostles Peter and Paul, was built in the cemetery during the 9th century. Now in ruins, it has left its place to the tombs. Only the apse of the little Romanesque chapel still remains, worn by rainwater and seepage.
Here, a unique testimony in the iconography of frescoes in Corsica slowly fades away: the representation of a brotherhood of women, probably originally protected by the mantle of the Virgin in Majesty, in the centre of the apse and carrying on her knees the infant Jesus, of whom a pretty naked foot can still be seen. ... the women's faces are tense in prayer, the hands joined, the silhouettes drawn with a sure line and evoke a universe close to the small fresco of the chapel of Santa Restituda in Calenzana. In 1967 Mrs Geneviève Moracchini already sounded the alarm, and in 1985 Mr Joseph Orsolini wrote that run-off water and seepage were degrading the magnificent 15th century fresco. In 1646 this small chapel served as the parish church of the village of Nessa. It was classified as a historical monument in 1990 and nothing has been done to restore it and protect it from wind and rain.
