The Church of San Juan de Berbío probably belonged to the monastery founded by Alfonso V in 1005; the Infanta Doña Urraca donated it to the Monastery of San Pedro de Eslonza in 1099.
The structure went through several redesigns in the fifteenth and sixteenth centuries. The most extensive was in the eighteenth century, which added square heads and porch trim. Of the original Romanesque design, all that remains are the basic building layout, the western facade double archivolt and bows and starts from the original facade. Until 1892, it was the parish church for Infiesto.
The church was destroyed by fire in 1936, during the Civil War, in which the eighteenth-century altarpiece was also burned.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.
