Mind Your Step Illusion By Erik Johansson, Sergel's Square, Stockholm, Sweden

Since its creation, Sergels torg has been much criticized for giving priority to cars at the cost of pedestrians. It has, among some quarters, become the main target for criticism of the much debated demolition of the central city district of Klara during the 1950s and 1960s. Nevertheless, it is not dissimilar to but larger than the public space in front of Centre Georges Pompidou in Paris and much like its French counterpart remains the most popular space in Stockholm for meeting friends, for political demonstrations, for a wide range of events, and for drug-dealers. This includes the fountain, in which people celebrate every major victory by a Swedish sports team.
History
Before the creation of Sergels torg, Brunkebergstorg was the most important public space in the area, the hub about which traffic revolved, the place where people would go to work and to find entertainment.
