The Cathedral (Duomo) of Cividale del Friuli was built in the 15th century over a pre-existing construction built in the 8th century. It is a Venetian Gothic building, finished in the 16th century by architect Pietro Lombardo, featuring interventions from the 18th century also. The interior houses an altar dedicated to the Madonna, in the right aisle, and the altarpiece of patriarch Pellegrino II (1195−1204), a silver retable which had been inscribed in Latin by the means of individual letter punches, 250 years before the invention of modern movable type printing by Johannes Gutenberg.
The Christian Museum annexed to the Duomo houses outstanding examples of Lombard sculpture. It contains some interesting relics of the art of the 8th century. The cathedral contains an octagonal marble canopy with sculptures in relief, with a font below it belonging to the 8th century, but altered later. The high altar has a fine silver altar front of 1185. The museum contains various Roman and Lombard antiquities, and works of art in gold, silver and ivory formerly belonging to the cathedral chapter.
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.
