[1] In August 1863, the construction of a new bank building started at Jagiellońska street 8, opposite the seat of the Prussian region.

Site plans were designed by architect Hermann Cuno: he built a three-storey edifice (dimensions 20x12m), with high storeys.

[1] Particular care was placed on building the vault, with all security measures available at the time such as reinforced walls, ceiling, windows and doors.

[1] In 1911-1912, the architect Otto Muller built an additional wing on the east, with two floors, to function as a residential house.

[1] The new hall communicated with the old building through a newly built corridor stretching parallel to Franciszek Ksawery Drucki-Lubecki street.

[2] As a result of a reorganization, a second branch of the National Bank of Poland in Bydgoszcz was established in 1951, a third was created in 1954, located at 4 Jagiellońska street.

[2] After another banking system reform in 1969, the NBP seat in Bydgoszcz took the role of controlling and financing (at national scale), various activities: small trade, industry, public utilities and housing.

The main portal is decorated with pilasters, and the whole building is topped with a wide frieze and a cornice with classicist and Renaissance details.
