To the north of Kauppatori Square stands the Presidential Palace, one of C. L. Engel’s grand neo-classical buildings. Originally at the beginning of 19th century, a salt storehouse stood on the site. The entire lot was bought by merchant Johan Henrik Heidenstrauch who built the first palace in 1820. He had to sell it to the senate of Finland in 1837 and the building was moved to the official residence of the Tsar or Russia (Imperial Palace of Finland).
The necessary rebuilding and furnishing work, carried out between 1843 and 1845, was directed by architect Carl Ludvig Engel, the creator of neoclassical Helsinki. The Imperial family of Russia visited in palace several times between 1854-1915.
During the World War I palace functioned as military hospital for Russian Army. In the Finnish Civil War (1918) it was first the headquarters of the Executive Committee of the Helsinki Workers and Soldiers Soviet. With the victory of the Whites, the Reds abandoned the Palace, which was temporarily used by German and White Finnish military staff. After the war it was quickly converted to the presidential palace of independent Finland. Complete repairs were made at speed, with the furnishings and art collections of the Palace being returned from storage in the National Museum and the Ateneum Art Museum, and also being supplemented. Since then, it has been the official residence of the President. The Palace was again refurbished and modernised by Martti Välikangas in 1938.
The Presidential Palace is open for tours, which can be arranged through Helsinki Expert.
The Church of Our Lady before Týn is a dominant feature of the Old Town of Prague and has been the main church of this part of the city since the 14th century. The church's towers are 80 m high and topped by four small spires.
In the 11th century, this area was occupied by a Romanesque church, which was built there for foreign merchants coming to the nearby Týn Courtyard. Later it was replaced by an early Gothic Church of Our Lady before Týn in 1256. Construction of the present church began in the 14th century in the late Gothic style under the influence of Matthias of Arras and later Peter Parler. By the beginning of the 15th century, construction was almost complete; only the towers, the gable and roof were missing. The church was controlled by Hussites for two centuries, including John of Rokycan, future archbishop of Prague, who became the church's vicar in 1427. The roof was completed in the 1450s, while the gable and northern tower were completed shortly thereafter during the reign of George of Poděbrady (1453–1471). His sculpture was placed on the gable, below a huge golden chalice, the symbol of the Hussites. The southern tower was not completed until 1511, under architect Matěj Rejsek.
After the lost Battle of White Mountain (1620) began the era of harsh recatholicisation (part of the Counter-Reformation). Consequently, the sculptures of 'heretic king' George of Poděbrady and the chalice were removed in 1626 and replaced by a sculpture of the Virgin Mary, with a giant halo made from by melting down the chalice. In 1679 the church was struck by lightning, and the subsequent fire heavily damaged the old vault, which was later replaced by a lower baroque vault.
Renovation works carried out in 1876–1895 were later reversed during extensive exterior renovation works in the years 1973–1995. Interior renovation is still in progress.
The northern portal is a wonderful example of Gothic sculpture from the Parler workshop, with a relief depicting the Crucifixion. The main entrance is located on the church's western face, through a narrow passage between the houses in front of the church.
The early baroque altarpiece has paintings by Karel Škréta from around 1649. The oldest pipe organ in Prague stands inside this church. The organ was built in 1673 by Heinrich Mundt and is one of the most representative 17th-century organs in Europe.
