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.
Holmen, Copenhagen
Being the oldest part of Holmen, Nyholm generally has the oldest buildings. These include the Central Guardhouse. The first guardhouse at Nyholm was located inside the Neptune Battery (now Sixtus Battery). When the building had become outdated and the grounds were being restructured, Naval Secretary Frederik Danneskiold-Samsøe proposed the construction of a new building to King Christian VI. The plans were approved in February 1744 and the project was assigned to Philip de Lange who served as Naval Master Builder for almost 30 years and also contributed with many other buildings at Nyholm, and the building was completed the following year. It guarded the passage between the Custom House and Nyholm. It was also used for receiving important guests to the naval base.
