Architecture in Stockholm
The buildings that survive from this period are mostly churches and royal buildings, since these were built from more durable materials than most other buildings from that period. Birger Jarls torn ("The Tower Of Birger Jarl") was considered the oldest building in the entire city, however, it is now known to have been erected by Gustav Vasa in the 16th century. The Riddarholmen Church from the late 13th century is considered to be the oldest surviving building in Stockholm. While it came to serve as the church of choice for royal burials, another church, the Storkyrkan ("Great Church") came to be used for coronations. Both of the churches have been redesign several times since their erection.
Architecture of Sweden
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 Stockholm 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.
