Parish Church of Saint Mark the Evangelist and Saint Thomas the Apostle

The present church was built between 1800 and 1852, when the five access steps and the large forecourt were also constructed. 

The neoclassical façade is tripartite, articulated by Doric pilasters and crowned by a pediment with a central oculus and a cross at the top. The central stone portal, with moulded lintel, is surmounted by a metal archiepiscopal coat of arms. 

On the left side of the church stands the square-plan bell tower. Its shaft features slit windows, horizontal string courses and clock faces. The belfry, with round-arched single openings, is topped by a square lantern echoing the same design, and by a four-pitched curved roof crowned with a metal cross and weather vane resting on overlapping ellipses.

A first small church is documented in 1360 in the Necrologio di Qualso. It became a sacramental church in 1463, following the separation of the parish of Tricesimo from the Collegiate Church of Udine. 

The church was enlarged in 1504, as attested by the date carved on the lintel of the door leading to the sacristy, and enriched with artworks commissioned from prominent artists. Among them was Bernardino da Bissone, active between 1498 and 1505 on the façade of the Cathedral of Tricesimo. He is said to have had a workshop in Vergnacco and donated a portal to the church, which was unfortunately sold to an antiquarian in 1889.

The interior consists of a single nave with a projecting rectangular presbytery and two lateral chapels near it. 

The niche for the pink marble baptismal font dated 1587 is located on the southern wall near the entrance.
The floor is composed of polychrome marble slabs arranged in geometric patterns and bands. 

A moulded cornice runs along the upper part of the nave and continues into the presbytery, resting on composite-style pilasters. Four rectangular windows above the cornice illuminate the nave. 

The presbytery, with a decorated ribbed cross vault and a rectangular plan with chamfered corners, is reached by three steps and lit by two rectangular windows. The original balustrades were removed and replaced with more recent wooden ones. 

On the left side of the presbytery is the door leading to the sacristy. The two side chapels flank the presbytery. At the centre of the nave, facing each other, are two access doors. 

Above the main entrance, on the counter-façade, stands the wooden choir loft with the organ. 

Further restoration works continued until the early 20th century, when the church officially became the parish church in 1906.
