Saint-Jacques Flamboyant Gothic tower is all that remains of the former 16th-century Church of Saint-Jacques-de-la-Boucherie, which was demolished in 1797, during the French Revolution, leaving only the tower. What remains of the destroyed church of St. Jacques La Boucherie is now considered a national historic landmark.
The tower's rich decoration reflects the wealth of its patrons, the wholesale butchers of the nearby Les Halles market. The masons in charge were Jean de Felin, Julien Ménart and Jean de Revier. It was built in 1509 to 1523, during the reign of King Francis I. With a dedication to Saint James the Greater, the ancient church and its landmark tower welcomed pilgrims setting out on the road that led to Tours and headed for the way of St James, which led to the major pilgrimage destination of Santiago de Compostela.
A relic of the saint preserved in the church linked it the more strongly and in modern times occasioned its listing in 1998 as a World Heritage Site by UNESCO among the sites and structures marking the the pilgrimage routes in France that led like tributaries of a great stream headed towards Santiago in the northwest of Spain.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.
