Mońki is a very young town that arose at the beginning of the 20th century. It owes its existence to the railway station between Białystok (the capital of Podlaskie Voivodeship) and Ełk. Mońki got the city rights (pl. prawa miejskie) in 1965. Then, the town was inhabited by about 3,000 people; now there are about 11,000 people. Lots of them went abroad to earn money for their families (especially to USA).
Near Mońki there are one of the greatest swamps in Europe, the Biebrza River Swamps, and in 1993 the government awarded the Biebrza National Park to preserve the unique nature. It is a great prop for rare birds like ruff (pol. battalion), which is a symbol of BNP.
