Norra Bantorget ("Northern Railway Square") is an area in central Stockholm, named after the location where the first Stockholm North Station was built. It is the traditional Social Democratic grounds of the Swedish capital. It is the location of the LO headquarters, the Swedish Trade Union Confederation. At Norra Bantorget is also the Workers Movement's Archive and Library, and Folkets hus (where Russian social democrats held their Fourth Congress in 1906).
