Karl Johans gate
Two old streets that only became one when parliament filled the gap in 1866 — Oslo's main artery is a seam in the city's history.

The western half was laid out in the 1840s as a royal avenue connecting the newly built palace to the city; the eastern half follows the line of Christian IV's original Oslo. When the parliament building was completed in 1866 at their junction, the whole length was united and named for the king who had died four years earlier. Walking it end to end covers the full arc of how modern Oslo was assembled.
What to look for
- Brynjulf Bergslien's 1875 equestrian statue of King Charles III John at the Royal Palace end — the namesake rendered in bronze
- The parliament building at mid-street, the precise hinge where two formerly separate thoroughfares were joined into one
- The eastern stretch near Oslo Cathedral, built over the ground where the old city ramparts once stood before being cleared away
Walk the full length in one go, from the Royal Palace at the west end down to the cathedral district at the east.
