Since the pre-Roman period, a fortified settlement has existed on the hill where Carcassonne now stands. In its present form it is an outstanding example of a medieval fortified town, with its massive defences encircling the castle and the surrounding buildings, its streets and its fine Gothic cathedral. Carcassonne is also of exceptional importance because of the lengthy restoration campaign undertaken by Viollet-le-Duc, one of the founders of the modern science of conservation.
Founded during the Gallo-Roman period, the citadel derives its reputation from its 3 kilometres long double surrounding walls interspersed by 52 towers. The town has about 2,500 years of history and has seen the Romans, Visigoths, Saracens and Crusaders. At the beginning of its history it was a Gaulish settlement then in the 3rd century A.D., the Romans decided to transform it into a fortified town. The Roman defences were in place by 333 AD. The original walls were supported by between 34 and 40 towers, spaced from 18 to 30 metres apart along the curtain wall. Each tower was semicircular in plan and about 14 metres tall. There were probably four main entrances to the town.
The Gallo-Roman walls were rebuilt during the town's occupation by the Visigoths in the 5th and 6th centuries, but the original structure remained in place. After 1226, an additional line of fortifications was added outside of the Roman walls. The town was finally annexed to the kingdom of France in 1247 A.D. It provided a strong French frontier between France and the Crown of Aragon. During this period, the inner, Roman walls were largely demolished and replaced, while the new outer walls were reinforced and extended to the south. The new towers built during this work were mainly circular, but two were square. Construction continued into the reign of King Philip IV in the early 14th century.
In 1659, after the Treaty of the Pyrenees, the province of Roussillon became a part of France, and the town lost its military significance. Fortifications were abandoned and the town became one of the economic centres of France, concentrating on the woolen textile industry.
In 1849 the French government decided that the city fortifications should be demolished. This decision was strongly opposed by the local people. Jean-Pierre Cros-Mayrevieille and Prosper Mérimée, an eminent archaeologist and historian, led a campaign to preserve the fortress as a historical monument. The government later reversed its decision and in 1853 restoration work began. The architect Eugène Viollet-le-Duc was charged with renovating the fortress. Viollet-le-Duc's work was criticised during his lifetime as inappropriate to the climate and traditions of the region. After his death in 1879, the restoration work was continued by his pupil, Paul Boeswillwald, and later by the architect Nodet.
The citadel was restored at the end of the 19th century and in 1997 it was added to UNESCO's list of World Heritage Sites.References:
Bergenhus fortress is one of the oldest and best preserved castles in Norway. It contains buildings dating as far back as the 1240s, as well as later constructions built as recently as World War II. The extent of the enclosed area of today dates from the early 19th century. In medieval times, the area of the present-day Bergenhus Fortress was known as Holmen (The islet), and contained the royal residence in Bergen, as well as a cathedral and several churches, the bishop's residence, and a Dominican monastery. Excavations have revealed foundations of buildings believed to date back to before 1100, which might have been erected by King Olav Kyrre. In the 13th century, until 1299, Bergen was the capital of Norway and Holmen was thus the main seat of Norway's rulers. It was first enclosed by stone walls in the 1240s.
Of the medieval buildings, a medieval hall and a defensive tower remain. The royal hall, today known as Haakon's Hall, built around 1260, is the largest medieval secular building in Norway. The defensive tower, known in the Middle Ages as the keep by the sea, was built around 1270 by King Magnus VI Lagabøte, and contained a royal apartment on the top floor. In the 1560s it was incorporated by the commander of the castle, Erik Rosenkrantz, into a larger structure, which is today known as the Rosenkrantz Tower.
In the Middle Ages, several churches, including the Christ Church, Bergen's cathedral, were situated on the premises. These however were torn down in the period 1526 to 1531, as the area of Holmen was converted into a purely military fortification under Danish rule. From around this time, the name Bergenhus came into use. Building work on the Christ Church probably started around 1100. It contained the shrine of saint Sunniva, the patron saint of Bergen and western Norway. In the 12th and 13th centuries it was the site of several royal coronations and weddings. It was also the burial site of at least six kings, as well as other members of the royal family. The site of its altar is today marked by a memorial stone.
In the 19th century, the fortress lost its function as a defensive fortification, but it was retained by the military as an administrative base. After restoration in the 1890s, and again after destruction sustained during World War II, Bergenhus is today again used as a feast hall for public events. During World War II, the German navy used several of its buildings for their headquarters, and they also constructed a large concrete bunker within the fortress walls. The buildings, including the Haakon's Hall, were severely damaged when a Dutch ship in the service of the German navy, carrying approximately 120 tons of dynamite, exploded on 20 April 1944 in the harbour just outside the fortress walls, but the buildings were later restored.
Bergenhus is currently under the command of the Royal Norwegian Navy, which has about 150 military personnel stationed there. The fortifications Sverresborg fortress and Fredriksberg fortress also lie in the centre of Bergen. Haakon's Hall and the Rosenkrantz Tower are open for visits by the public. Koengen, the central part of Bergenhus Fortress is also known as a concert venue.
