The eighteenth-century neoclassical façade features an undulated cornice and a large doorway of classical lines with a Baroque style niche that hosts the image of Saint Nicholas of Bari and a rose window that illuminates the interior of the nave. Note the portal and the cladding on the central parts in white-gray marble. To the left of the facade, there is a solid octagonal bell tower, also raised in the eighteenth century, which remains unfinished.
