Agde Cathedral is dedicated to Saint Stephen and stands on the bank of the Hérault River. The present building was constructed in the 12th century, beginning in 1173 under the direction of bishop William II of Agde, and replaced a Carolingian church of the 9th century that stood on the foundations of a 5th-century Roman church, formerly a temple of Diana.
The cathedral is remarkable for being built of black basalt from the nearby volcanic Mont St. Loup quarries. The building is extremely strong and was designed to serve as a fortress as much as a church: the walls are between 2 and 3 metres thick, and the square tower, 35 metres high, could also function as a keep, or donjon. The crenellations and machicolations are very prominent, and again, more characteristic of a fortress than of a church.
The Romanesque cloister which once adjoined the cathedral was demolished in 1857. Many of the materials, such as the capitals and the columns, were shortly afterwards reused for the construction of the lady chapel, which is now used as the entrance.
In the severe interior the 17th century high altar of polychromatic marble stands out all the more, as do the organs in Baroque style.
Of the cathedral's five bells, four are hung in the belltower, and were cast by Burdin-Aîné of Lyon in 1894 and 1895. The fifth is on top of the bellower and is used only for the chiming of the clock, cast in 1665 by Daniac Fulcrand at Béziers, and declared a monument historique in 1959.
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.
