The Brunkeberg Tunnel in Norrmalm, Stockholm, is a 231-metre-long passageway for pedestrians through the esker Brunkebergsåsen. The tunnel was inaugurated in 1886 by King Oscar II. On this end of the tunnel (Sveavägen side) you’ll find the Hötorget T-Banna (subway) and a plaque memorizing the location where the Swedish Prime Minister was murdered in 1986.

Carl Lindblom has blessed the inside of the Brunkeberg Tunnel with his mandolin music nearly everyday since 1987. No matter how often you walk through the Brunkeberg tunnel, it’s pretty cool, especially when Mr. Lindblom is strumming the strings!
