Once the location of one of Kreditbanken’s (The Credit Bank) offices this place became the birthplace of Stockholm syndrome.

In August 1973 Jan-Erik Olsson, a convicted criminal on leave from prison, tried to rob the bank taking four hostages. His friend from prison Clark Olofsson joined him and the hostage drama continued for five days. During this time the hostages bonded with the robbers and started showing sympathy for them. After being released, the hostages defended their captors and would not agree to testify in court against them.

The condition which causes hostages to develop a psychological alliance with their captors during captivity became later known as the Stockholm syndrome.

Today, there is a hotel and an upscale restaurant in the building. The boreholes made by the police back in 1973 are replenished but still visible inside the hotel.
