The oldest part of the presently visible church at När is the tower, erected at the middle of the 13th century. Originally, it was designed to be able to function as a defensive tower, with arrowslits still visible on the first floor. The present nave and choir of the church were added to the tower around the year 1300. Of an earlier, Romanesque church on the same site no traces remain today.
Externally, the church has two portals decorated with stone sculptures on the southern façade. Internally, the nave is divided in two by two central columns. Among the furnishings, the Romanesquebaptismal font is the oldest. It was made by the sculptor known as Hegvald and its sculptured reliefs display religious motifs. The church also has a late medieval triumphal cross. Other furnishings are mostly from the 17th and early 18th centuries. In one of the lychgates leading to the church, a decorated tombstone from 1322 is displayed.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.
