The site south of the square is taken up by the cultural centre Kulturhuset, which also harbours the Stockholm City Theatre and hides the Bank of Sweden headquarters facing the square Brunkebergstorg behind. The street Klarabergsgatan leads west past the department store Åhléns City and Klara Church to the Klaraberg Viaduct and Kungsholmen. Hamngatan leads east under Malmskillnadsgatan to Kungsträdgården, Norrmalmstorg, and Strandvägen. Together with the underground mall east of the pedestrian plaza and the T-Centralen metro station and other continuous underpasses west thereof, Sergels torg forms part of a continuous underground structure almost a kilometre in length.
