The church is located in the centre of the old village opposite from the Upper Gate (Gornja Vrata) on the square. It was built in 1650 during the Siege of Candida and the plague, and it is dedicated to the Virgin Mary as an symbol of gratitude for protecting the place of the plague. It is also a testimony of the centuries old connection of the people of Sukošan with the Virgin Mary who protected them during troubled times.
The church has built loop holes which lead us to the conclusion that it also served as a protective edifice in front of the town’s gate. Furthermore, what is very interesting are the door-posts, two pre-Romanesque epistyles. These are reliefs from the 9th and 10th century and undoubtedly originate from the St. Cassian’s Church.Once, there was a cemetery around the church.
