Zilia church can be found in the heart of the village. It is dedicated to Saint Roch, or San Roccu, a highly venerated saint in Balagne.
The Baroque-style St Roch church was completed in 1688 and then extended in the 19th century. A municipal decree dated 1651 reflects the decision to build it.

Its high polychrome marble altar comes from the Alzipratu convent. He was
recovered by the inhabitants, in the 18th century as well as the statue of Saint
François dei maleficii and the statue of San Bonavintura.

San Roccu treated plague victims, his cult developed in the 15th century following terrible plague epidemics.
