The Houses of Estonians have been made in wood already thousands of years. Wooden architecture is one of the most important stage in our history of architecture and it is still existing in such a extend that it is possible to get complete overview. That is unique in European context, where it is difficult to find still existing similar districts. There are wonderful centrums with historical wooden constructions in towns such as Paide, Viljandi, Võru and Valga, where the wooden houses are dominantly from the end of 18th and beginning of the 19th century. Massive wood-construction reached its peak on beginning of the 20 century and from that period there is considerable number of complete villages and downs. For example, Kilingi-Nõmme, Kadrina, Lihula, etc, where next to main roads there are wooden houses and wooden societal buildings. For example, the most expressive example of wooden architecture in Tartu is city district of Karlova, which is the impressive example of wooden architecture in first decade of the 20th century. The buildings are characterised by many decomposed outward parts of roof and gables, jugendstil facades, which are modified for the wood architecture and which are mainly made with round shaped frames around doors and windows. The value of wooden architecture in Estonia consist in its unique multiplicity and variety. Almost in every historic district of city there is still existing a building, or group of buildings which is unique for that district.
