Karl Johanslussen, Maritime lock in Slussen district, Stockholm, Sweden
The Karl Johanslussen lock connects Lake Mälaren to the Baltic Sea through a 75-meter-long and 10-meter-wide concrete structure reinforced with steel.
The current lock, inaugurated in 1935, represents the fourth iteration of locks at this location, following Queen Christina's Lock from 1642.
The lock area transformed from a commercial shipping route to a focal point for pleasure boats and sightseeing vessels in the 1920s.
The lock system accommodates vessels up to 3.8 meters in height and maintains a depth of 3.90 meters throughout its length.
The lock employs a specialized gate mechanism that functions independently of water pressure, setting it apart from traditional lock designs.
