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:
From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia"s rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.
