The church of S. Caterina d’Alessandria Vergina can be found in the town of Mores. It was built around 1630 and completed in 1636, when worshipping began there. The facade, however, was not completed until 1670 thanks to a financial contribution from the Marquis of Mores.
The main facade has a wall face in carefully cut limestone calcarenite; it is divided up horizontally by a moulded cornice, while the upper part ends in a curvilinear style like the church of Gesù and Maria in Sassari; all the other facades have been plastered. In the middle is a portal with rounded arch resting on two half pilasters, while higher up there is a rectangular window.
The building features an imposing square-shaped bell tower which houses the bell chamber with eight columns resting on plinths on the top level. Further up is a cornice supported by a cylindrical lantern decorated with garlands.
The layout of the church is single nave with side chapels which were very popular in the seventeenth century. The nave is split into three rounded arches resting on grouped pillars. The chapels and presbytery are preceded by rounded arches which are highlighted by the exposed wall. Overall, it is mostly plastered and painted, except the presbytery.
