- The city was founded in 1680 specifically to serve as the main base for the Swedish Navy, chosen for its deep-water harbor and strategic position in the Baltic Sea.
- Karlskrona is the only city in Sweden that was intentionally planned and built from scratch to function as a naval fortress.
- The city's street layout was designed with wide boulevards to allow for the rapid movement of troops and the easy transport of heavy naval equipment in the 17th century.
- Large portions of the city are constructed on reclaimed land, requiring significant engineering efforts during the late 17th century to accommodate the naval infrastructure.
- The naval base remains active today, making Karlskrona one of the few places where historic military architecture and modern naval operations coexist in the same historical site.
