Norra Bankohuset, Bank building in Gamla Stan district, Stockholm, Sweden

Norra Bankohuset is a two-storey stone building at Österlånggatan 53 and Skeppsbron 42A in Gamla Stan, Stockholm. Its plain plastered facade has a warehouse-like character, while the Skeppsbron side, designed by Johan Fredrik Åbom in 1856, features broad band-rusticated pilasters and pedimented window surrounds. A covered footbridge, known as the "Bridge of Sighs", links it to the Södra Bankohuset across Norra Bankogränd.

The Riksbank bought the site, then occupied by the Alardiska huset, from Simon Bernhard Hebbe in 1772 and replaced it with a two-storey building designed by Carl Johan Cronstedt. Extensions by Carl Christoffer Gjörwell the younger in 1803 and 1824 added a storey and a footbridge over Norra Bankogränd. Johan Fredrik Åbom redesigned the Skeppsbron facade in 1856.

The walkway over Norra Bankogränd, added in 1818, carried banknotes between the bank's offices and its note store. It is popularly called "Suckarnas bro" (Bridge of Sighs) because it recalls the Venice bridge of that name. The building's plain, smooth-plastered facade still reads as a storehouse.

The building sits in a central location within Gamla Stan that is easy to reach on foot from nearby streets. Access to view the exterior is straightforward, though visitors should be aware this is a historic structure with limited interior access.

An old shoreline between solid and loose ground runs through the middle of the block, and its settlement shows in the facade toward Norra Bankogränd, where the crack passes straight through a window.
