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.
The Glaucus Block
The oldest mention of the buildings in the block is from the year 1420, where there was two stone houses along Österlånggatan. Between the houses, a now-abandoned alley went through the block. By the water lied a wooden keep, it was torn around the year 1430. Later during the 1400s, Sten Sture the Elder let the elderly begin the foundation work for a building, probably intended as a warehouse, in the southwest part of the block. The Construction project is mentioned in Stockholms tänkebok (a type of protocol book used in the medeival period) from the year 1492. Construction stalled in 1495 as the area was hit by a massive fire.
