The church is an example of Baroque architecture built in the 14th century, and has been repeatedly amended over time. It was built with material from a nearby Roman theater and had a gabled façade. Over the centuries it underwent a major restoration and the church assumed its present Baroque appearance. The single nave interior preserves a crucifix of the 14th century. In a lateral niche is the silver bust of St. Nicandro with a some relics of martyrs. The church also has a large frescoed dome, visible from every point of the city.
