Agen Cathedral's (Cathédrale Saint-Caprais d'Agen) visible structure dates back to the 12th century. It was built as a collegiate church of canons dedicated to Saint Caprasius, on the foundations of a basilica sacked by the Normans in 853 but thereafter restored.
Sacked again in December 1561 during the Wars of Religion, by two years after the countrywide coup d'état that took place in 1789, the cathedral had come to store fodder before being reopened in 1796 and being elevated to the status of the city's cathedral in 1801. This new cathedral replaced the old cathedral in the town, which was destroyed during the French Revolution, thereby becoming the bishop's seat in the diocese.
The cathedral appears in one of the earliest color photographs ever taken by Louis Arthur Ducos du Hauron in 1877.
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.
