Kungsportsplatsen is a square in downtown Gothenburg, Sweden. The square was built in 1852 and was named after the King’s Gate. The gate was the main entrance to the fortified city, which was and is surrounded by a moat. When the city grew outside the moat and it was no longer necessary to defend the city, the gate was demolished. In Kungsportsplatsen there is a statue of King Charles IX, which was erected there in 1936.
