The Presidential Palace is one of the three official residences of the Republic of Finland. It is located on the north side of Esplanadi, overlooking the Market Square, in Helsinki.
At the beginning of the 19th century, there was a sweet shop on site. Johan Henrik Heidenstrauch, one of the merchants of Helsinki, bought a whole lot and built revising 1816-1820 between the architects, a grand residence designed by Pehr Granstedt.
Heidenstrauch house looks more like a palace than a business house. In 1837, it became a palace for the price of 170 000 rubles, transformed into a residence for Finland's governor-general. However, Nicholas I want him to become the official residence of Helsinki, Grand Duchess of Russia's Tsar of Russia/Grand Duke of Finland, and the building becomes the royal palace in Helsinki. The necessary rebuilding and equipped work between 1843 and 1845, producer Karl Ludvig Engel, the producer of Neoclassical Helsinki and after his death, directed his son Carl Alexander. All the wood mounds in the past were broken and added a new wing.
