Kungsgatan was dug through the Brunkebergsåsen esker (a natural ridge) in the early 20th century and inaugurated in 1911.
In the central-northern part of Stockholm, the Brunkebergsåsen, divided the Norrmalm district in an eastern and western part, Östermalm and Västermalm, and Malmskillnadsgatan is a street passing along the top of the ridge.
