[1] The church, dedicated to Saints John and Paul, was built on the remains of a previous sacred building with three apses and was consecrated by the Bishop of Trieste Arlongo dei Visgoni on 29 December 1263.

[2] The Romanesque building was augmented, in the middle of the 15th century, by the cladding of the facade in white stone slabs, an example of Gothic-Venetian style.

[5] The facade is in white stone with reliefs in the lunette of the portal; the whole is dominated by an imposing rose window in typical Gothic style.

The facade has a rose window in the upper part with the image of the Madonna and Child in the center surrounded by three epigraphs.

In the lower part, two elegant and slender Gothic windows flank the portal, on which is superimposed a lunette with an inflected arch, inside which an original representation of the Holy Trinity adored by Saints John and Paul is located in high relief.
