History of Finland
The history of Finland begins around 9,000 BC during the end of the last glacial period. Stone Age cultures were Kunda, Comb Ceramic, Corded Ware, Kiukainen, and Pöljä cultures. The Finnish Bronze Age started in approximately 1,500 BC and the Iron Age started in 500 BC and lasted until 1,300 AD. Finnish Iron Age cultures can be separated into Finnish proper, Tavastian, and Karelian cultures. The earliest written sources mentioning Finland start to appear from the 12th century onwards when the Catholic Church started to gain a foothold in Southwest Finland.
Architecture of Finland
1249 is the date normally given for the beginning of Swedish rule over the land now known as Finland (in Finnish, "Suomi"), and this rule continued until 1809, after which it was ceded to Russia. However, under Russian rule it had a significant degree of autonomy as the Grand Duchy of Finland. Finland declared independence from Russia in 1917, at the time of the Russian Revolution. These historical factors have had a significant bearing on the history of architecture in Finland, along with the founding of towns and the building of castles and fortresses (in the numerous wars between Sweden and Russia fought in Finland), as well as the availability of building materials and craftsmanship and, later on, government policy on issues such as housing and public buildings. As an essentially forested region, timber has been the natural building material, while the hardness of the local stone (predominantly granite) initially made it difficult to work, and the manufacture of brick was rare before the mid-19th century. The use of concrete took on a particular prominence with the rise of the welfare state in the 1960s, in particular in state-sanctioned housing with the dominance of prefabricated concrete elements.
