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.
Stumholmen
Stumholmen is a small island to the east of Trossö in Karlskrona, Sweden. It is connected to the center of Karlskrona by the Bastionsgatan bridge. Formerly the property of the Navy, today it houses the National Naval Museum (Marinmuseum), one of Sweden's oldest founded in 1752, the Hyper Island educational complex, and several other historic buildings. The unusual "Slup- och barkass- skjulet" (Sloop and Longboat Shed) is noted for its remarkable roof while buildings on Laboratorieholmen once served as an isolation hospital when the town was struck with disease. Comprehensive restoration and renovation work has been undertaken since the 1990s, providing a variety of interesting sights for tourists as well as residential accommodation for senior citizens. Since 1998, the Naval City of Karlskrona, of which Stumholmen is a key component, has been a UNESCO World Heritage Site.
