Nancy Cathedral was built at the beginning of the 18th century by architects Jules Hardouin-Mansart and Germain Boffrand. Several paintings by local artists from the 17th and 18th century are exhibited.
The great organ of the cathedral of Nancy has been built from 1756 by Nicolas Dupont. One century later (1861), Aristide Cavaillé-Coll signed here its biggest work in France outside of Paris.
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.
