The Duomo of Santa Maria ad Nives is a Roman Catholic church, formerly cathedral, located in Atella. The church has undergone a number of reconstructions and contains an eclectic array of styles. The stone façade dates to the 13th century with a gothic-style portal and rose window, but the interiors were completed mainly in the 18th-century. The façade has statues of St Anthony Abbot and San Nicola di Bari. The interior has altarpieces depicting the Annunciation (circa 1500) and a Madonna della Neve from 1800.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
