Belavezhskaya Pushcha, is an ancient woodland straddling the border between Belarus and Poland, located 70 km (43 mi) north from Brest (BE). It is one of the last and largest remaining parts of the immense primeval forest which once spread across the European Plain.
This UNESCO World Heritage Site and Biosphere Reserve lies in parts of the Brest voblast (Kamianiec and Pruzhany districts, BE) and Hrodna Voblast (Svislach district) in Belarus and on the Poland side near the town of Białowieża in the Podlaskie Voivodeship (62 km (39 mi) south-east of Białystok (PL) and 190 km (120 mi) north-east of Warsaw).
The border between the two countries runs through the forest and is closed for large animals and tourists for the time being. The forest is home to 800 wisent, the continent’s heaviest land animals. The security fence keeps the wisent herds physically and genetically separated.
