Founded in 1448, the Church of San Domenico combines Renaissance and Medieval elements. Its most interesting feature is the rose window defined by 16 little tuff columns. The wooden portal (1614) is inlaid with floral motifs, figures of saints and coats of arms. Inside the church are works by the sanfilese painter Antonio Granata such as the canvas depicting the Madonna of the Rosary between Saints Dominic and Agnese da Montepulciano preserved in the ancient choir used today as a sacristy in the church (late 18th century). The high altar is made of polychrome marble (1767). In the transept, there is a Deposition and a San Vincenzo Ferreri (late 18th century, anonymous). The sacristy is noted for its ribbed vault, a double lancet window with a narrow arch and a wooden choir installed in 1635.
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.
