First record of Hatanpää dates back to year 1540 and the first manor was built in the 1690s. Hans Boije (1717-1781) improved the farming business and increased Hatanpää prosperity significantly. He also built an English garden to Hatanpää with and hired 30 gardeners to maintain it. Boije was a freemasonry and added an stone to the park with Greek engraving Egno Kyrios tous ontas antou (Lord knows his owns). The stone still exists and is known as the “grave of the freemasonry”, but no one is actually buried there.
After Boije Hatanpää manor has been owned by several families. The original main building burned in 1883 and the present one Neo-Renaissance manor was built in 1883–1885. There’s also an another Neo-Gothic manor nearby. It was built in 1898-1900 as the villa for the banker and manor owner Nils Idman. Idman was forced to sell all Hatanpää manor property to the city of Tampere in 1913. The manor was in hospital use until the new hospital was built nearby in 1930s.
Today Hatanpää manor can be booked for parties or conferences. Near the manor are beautiful rose garden and arboretum, which are very popular in the summer time.
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.
