Bergen Cathedral was first time mentioned in 1181. It retains its ancient dedication to St. Olaf. During the reign of king Haakon IV of Norway, a Franciscan friary was established near the church, then known as Olavskirken, or the church of Saint Olaf, which was incorporated in it. The church burned down in 1248 and again in 1270, but was reconstructed after both fires. In 1463, it burned down again, but this time it was not reconstructed until the 1550s, despite being declared the cathedral in 1537.
After the fires of 1623 and 1640, Bergen Cathedral received its current general appearance. The steeple on the nave was torn down, and the current tower was built. During the renovation in the 1880s by architect Christian Christie, the Rococo interior was replaced to give the interiors back their former medieval appearance.
A cannonball from the 1665 Battle of Vågen between the English and Dutch fleets remains embedded in the cathedral's exterior wall. The present organ at Bergen Cathedral, by Rieger Orgelbau, is from 1997. The organ is the fifth one in the cathedral's history; the first known organ was installed in 1549.References:
The Château d'Olhain is probably the most famous castle of the Artois region. It is located in the middle of a lake which reflects its picturesque towers and curtain walls. It was also a major stronghold for the Artois in medieval times and testimony to the power of the Olhain family, first mentioned from the 12th century.
The existence of the castle was known early in the 13th century, but the present construction is largely the work of Jean de Nielles, who married Marie d’Olhain at the end of the 15th century.
The marriage of Alix Nielles to Jean de Berghes, Grand Veneur de France (master of hounds) to the King, meant the castle passed to this family, who kept it for more than 450 years. Once confiscated by Charles Quint, it suffered during the wars that ravaged the Artois. Besieged in 1641 by the French, it was partly demolished by the Spaniards in 1654, and finally blown-up and taken by the Dutch in 1710. Restored in 1830, it was abandoned after 1870, and sold by the last Prince of Berghes in 1900. There is also evidence that one of the castles occupants was related to Charles de Batz-Castelmore d'Artagnan, the person Alexandre Dumas based his Three Musketeers charictor d'Artagnan on.
During the World War I and World War II, the castle was requisitioned first by French troops, then Canadian and British soldiers. The current owner has restored the castle to its former glory.
