This 1820 map of Vilnius Province is from a larger work, Geograficheskii atlas Rossiiskoi imperii, tsarstva Pol'skogo i velikogo kniazhestva Finliandskogo (Geographical atlas of the Russian Empire, the Kingdom of Poland, and the Grand Duchy of Finland), containing 60 maps of the Russian Empire. Compiled and engraved by Colonel V.P. Piadyshev, it reflects the detailed mapping carried out by Russian military cartographers in the first quarter of the 19th century. The map shows population centers (six gradations by size), postal stations, roads (four types), state, provincial and district borders, taverns, and customs outposts. Distances are shown in versts, a Russian measure, now no longer used, equal to 1.07 kilometers. Legends and place-names are in Russian and Polish. The territory depicted on the map corresponds to parts of present-day Lithuania and Belarus. It includes the city of Vilnius, also seen as Vilna, which since 1323 has been known as the historical capital of Lithuania formed under Gediminas, the Grand Duke of Lithuania (died 1341). In 1569 the territory became a large city within the Polish-Lithuanian Commonwealth. Vilnius Province was established within the Russian Empire after the Third Partition of Poland in 1795.
