Wizna is a village in Łomża County of Podlaskie Voivodeship, in north-eastern Poland. The Biebrza River flows through town. Wizna is also known for the battle of Wizna which took place in its vicinity during the 1939 Invasion of Poland. At present, farming and food production are the primary sources of income for the residents. The food production by private farms provides favorable conditions for the development of processing industry.
Wizna has a remarkably rich history. Already in the 11th century there was a castle there watching over the eastern border of Masovia and the important river crossing over Narew. From the mid 12th century the town was a registered office of the castellany, and from 1379 the capital of the Ziemia wiska ( Wizna Land) bordering both Prussia and Lithuania. The Catholic Parish in Wizna was established in 1390.
