European bison in the natural habitat

Białowieża Forest is an ancient woodland that straddles the border between two countries, Belarus and Poland. It is known as Belovezhskaya Pushcha in Belarusian, and as Puszcza Białowieska in Polish. It is located 70 km (43 mi) north of Brest (Belarus) and 62 km (39 mi) southeast of Białystok (Poland). It is one of the last and largest remaining parts of the immense primeval forest that once stretched across the European Plain.
