The Baroque Church of St. Nicholas in Bellegra comprises a presbytery and a single chamber.
The main arch is inscribed with the dedication: LAUS DEO, BEATAE VIRGINI MARIAE ET S. NICOLAI ECCLESIAE PATRONO.
The interior is artistically decorated with pre-1671 stucco work, while the barrel vault covering the nave replaced the previous coffered ceiling in 1873. The church holds some 17th century frescoes and engravings.
It is lit by seven large windows, one on the front wall, and three on each side.
