The Church of Poble Vell, built next to the castle, is cited in a 1154 document as a parish of Sòrisa. It is a religious building of rectangular plant, with a bell tower and apse. The ensemble formed by the Castle and the Church is one of the most characteristic images of Súria.
Initially, the Church had a single nave and it was of Romanesque style. The other elements of the church have come from enlargements and more modern alterations. The most noted one was in 1862, when the two lateral naves were added.
The temple used to have an important Baroque altarpiece, dedicated to Saint Cristopher, which was destroyed in 1936, at the beginning of the Spanish. Civil War.
Inside the apse, a mural painting from the 15th century, representing a bell ringer, has also been recovered.
