Climate
Helsinki is among the world's northernmost capitals and the lengthy winter, from October all the way up to April, is dark and freezing. Winter temperatures average -5°C, but the wind chill makes it feel even colder and the mercury can plunge below -20°C on a particularly cold day. Snow falls only intermittently and often melts into gray slush.
The summer is often pleasant, but brutally short, lasting from early June until mid-August. Temperatures are usually around 20°C and sometimes climb above 25°C. Parks burst into green and sunbathers dot the city's beaches. Due to the northern latitude, the daylight hours are unusually long in summer, with sunsets very late in the evening, and virtually no darkness at night from early June until mid-July.
History
Helsinki was founded in A.D. 1550 by King Gustav Vasa of Sweden as a trading post to compete with Tallinn to the south in Estonia, which was Danish at that time. The growth of the city was slow until the establishment of Sveaborg nowadays Suomenlinna Maritime Fortress in the front of Helsinki in the middle of 18th century. In 1809, Finland was annexed by Russia during a war of that period and the capital of Finland moved from Turku to Helsinki in 1812. The Czar felt the Grand Duchy of Finland needed a capital of grand proportions. The architects Johan Albrecht Ehrenström, a native Finn, and Carl Ludwig Engel, from Germany, were given the task of rebuilding the city in the Empire style. This can be seen today around the Lutheran Cathedral, which was completed in 1852. The same style, and even architects, is also a part of Saint Petersburg's history. Though thoroughly a Nordic capital, Helsinki today reflects the influences gained from the Western and Eastern cultures.
