This article covers the architecture of Sweden from a historical perspective.
As is the norm in architecture history, an architectural history of a nation naturally lends itself to a history of those monuments to the development of that nation and its institutions of power; palaces, castles, and churches. This also applies in the case of the history of architecture in Sweden being related here. The break comes with the modern era, with the change in the role of architects in society, towards a concern with questions concerning the entire population, such as housing and the infrastructure of a social democracy.
In Sweden, the Middle Ages lasted for approximately 500 years, from the baptism of Olof of Sweden in 1000 AD until Gustav I of Sweden seized power in 1523. At first almost all buildings, urban and rural, were constructed of timber. In the 12th century, stone became the predominant building material for the construction of Romanesque monasteries and churches. Notable examples are Lund Cathedral, Sigtuna monastery, Husaby Church and Alvastra monastery. The smaller Romanesque churches in the countryside were often fortified.
The advent of the Gothic style brought brick to Sweden as a new building material. The cathedrals of Västerås, Strängnäs and Uppsala were all constructed of brick, whereas the cathedrals of Skara and Linköping were made of limestone.
While about 1,500 of Sweden's 4,000 churches date to the Middle Ages, very few secular buildings survive from this period. There are however a few Burgher's houses in and Visby, some castles, fortresses, and fortifications. The 13th century city walls around Visby are some of the best-preserved medieval city walls in Europe. The street layout of Stockholm's Old City is still medieval. In other Swedish cities secular buildings from the Middle Ages are very rare and often heavily rebuilt during the following centuries. One example of that is Skytteanum in Uppsala.
