As a result of the third partition of Poland, Białystok became part of the Kingdom of Prussia. Shortly after 1794, the city became the seat of the Białystok department of the province of New East Prussia. The highest administrative authority was located here - the Camera of War and Domains, which in 1799 commissioned the conductor George Becker to carry out measurements of Białystok. It is possible that the creation of this plan was related to the process of purchasing the city from Branicki's heirs and it was intended to serve as a precise inventory of the actual state, which was used primarily to clarify the principles and scope of the city's lease. The plan shows Białystok within the borders marked in the 18th century with a fence and soft gates, and the accompanying suburbs of Choroskie and Warsaw, as well as the palace and garden complex with part of Zwierzynców. The plan only partially notes the functions of the buildings in the city and - importantly - gives the street names established by the Prussians. Until 1802, when the sale of the Białystok estates to the Prussian king Frederick William III was finalized, the possibilities of the Prussian authorities in terms of construction investments or urban planning activities in the city were very limited. However, on George Becker's plan one can see the regulatory lines of development introduced by the Prussian authorities along Wasilkowska Street and the Grodno route (today Sienkiewicza Street) and the entire today's Warszawska Street. The plan also proposed locations for the designed buildings, including: at the Grodno route, at Bojarska Street (Warszawska Street) - this is where the post office building was to be built - and in Przedmieście Warszawskie (near today's intersection of Warszawska and Swietojanska streets). An important novelty noted on George Becker's plan is the circular numbering of buildings throughout Białystok, which was used by the Prussian authorities to organize the city space and facilitate tax collection. The plan distinguishes between wooden (black) and brick (red) buildings, and areas separated from municipal jurisdiction (beneficiary of Catholic and Uniate churches) and manorial properties are indicated in gray. A comparison of the plan from 1799 with the city inventory from 1771 proves that there have been no major changes in the development of Bialystok since the death of Jan Klemens Branicki. Only after 1802 could the Prussian authorities begin to freely organize the urban space and implement large investment projects in order to transform the former private town of the Branicki family into the administrative center of the Prussian province.
