Norrmalmstorg is a public square located in the heart of Stockholm, Sweden. It is surrounded by notable buildings, including the Nordiska Kompaniet department store and the Royal Swedish Opera. The square serves as a popular meeting place and is often used for events and public gatherings. The area gained international attention in 1973 during the Norrmalmstorg robbery, where hostages were taken in a bank. This incident led to the term "Stockholm syndrome," describing the bond that can develop between captives and their captors. Today, Norrmalmstorg remains a vibrant part of the city's urban landscape.
