Mazovian Lowland

The Mazovian Lowland (Polish: Nizina Mazowiecka, pronounced [ɲiˈʑi.na ma.zɔˈvjɛt͡s.ka]), also known as the Masovian Plain, is the largest geographical region in central Poland, roughly covering the historical region of Masovia. Sometimes it is also categorized as including Mazovian-Podlasian Lowlands which together form part of the greater North European Plain.

The Plain is located in the valleys of three large rivers: Vistula, Bug and Narew. Although relatively densely populated and urbanized, the Mazovian Lowland is covered by several large forest complexes that once were a part of a dense primaeval forest covering much of Poland: Kampinos Forest, Kurpie Forest, White Forest, Kozienice Forest and Green Forest. Until the mid-17th century it was also the home of the last documented aurochs herds.
