Thiene Cathedral replaced a previous church of the Assumption which apparently dated from before 1166. Construction was completed by 1314. It was rebuilt in 1625, and was substantially altered in the late 18th century by architect Ottone Calderari. The dome was not added till the 1930s. The nave ceiling is decorated with 15 paintings by Baroque Venetian painters, including Giulio Carpioni and Giovanni Battista Pittoni.
Next to the church is the tall obelisk-like bell tower, designed by Sebastiano Serlio, beyond which is the Church of the Rosary built in 1685 in a staid Baroque style. This church contains stucco and painted decorations by the local artists Ballante (1657-1729) and Valentino Bassi (17th century). The main altarpiece was painted in 1590 by Matteo Grazioli. The painting of the Annunciation in the north aisle was painted by the school of Alessandro Maganza (1509-1589). There are some ancient frescos, restored in the 1700s, of the 'Madonna delle Grazie' and a marble statue of Saint Joseph by Orazio Marinali.
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.
