The written history of Laukko manor dates back to year 1416, but according the folklore the local chieftain Matti Kurki received it as a manor from the king of Sweden in the 13th century. The most famous of the medieval lords of Laukko was Klaus Kurki, the tragic hero of a ballad called The Death of Elina. In real life Klaus’s son Arvid became the last Bishop of Catholic Finland. At around the beginning of the 16th century the Kurcks had a stone castle built at Laukko as a symbol of their might and prosperity. The Kurki family owned Laukko until 1817. After that it has been owned by several families, for example famous industrialists Adolf Törngren and Rafael Haarla. Nowadays Laukko is a residence of the Lagerstam family.
The present neo-classic manor house was built in the 1930s. The estate reopened to the public in the summer of 2016, as the estate celebrates its 600th anniversary. For the first time, visitors can see the estate in its entire splendor. The visitors can now admire the main building’s unique collections of arts and antiquities and stroll in the estate’s vast gardens and grounds.
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
