Senate Square (Senaatintori) presents Carl Ludvig Engel's architecture as a unique allegory of political, religious, scientific and commercial powers in the centre of Helsinki. It has been the centrum of Helsinki since the city was established in 1640. Russians destroyed Helsinki entirely during the Great Northern War (1713-1721).
When the Finland became an autonomous part of Russia in 1812, the capital was moved from Turku to Helsinki. This started a massive construction programme to enhance the cityscape of Helsinki. The responsibility of the new design was given to German architect Carl Ludvig Engel. He decided that all buildings surrounding the old main square should be reconstructed to solid neoclassical ensemble. Many old buildings were demolished including the church of Ulrika Eleonora.
The Palace of the Council of State was completed on the eastern side of the Senate Square in 1822. The main University building, on the opposite side of the Senate Square, was constructed in 1832. The Helsinki Cathedral on the northern edge of the Senate Square was Engel's lengthiest architectural project. He was working on it from 1818 until his death in 1840. The Helsinki Cathedral — then called the Church of St. Nicholas — dominates the Senate Square, and was finalized twelve years afters Engel's death, in 1852.
A statue of Emperor Alexander II is located in the center of the square. The statue, erected in 1894, was built to commemorate his re-establishment the Diet of Finland in 1863, as well as his initiation of several reforms that increased Finland's autonomy from Russia. The statue comprises Alexander on a pedestal surrounded by figures representing the law, culture and the peasants.
Today, the Senate Square is one of the main tourist attractions of Helsinki. Various art happenings, ranging from concerts to snow buildings to controversial snow board happenings, have been set up on the Senate Square. Several buildings near the Senate Square are managed by the government real estate provider, Senate Properties.
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.
