3252 POLAND (Podlaskie) - The Augustów Canal (UNESCO WHS - Tentative List)

The Augustów Canal (Kanał Augustowski) is a cross-border canal built in the 19th century in the present-day Podlaskie Voivodeship of northeastern Poland and the Grodno Region of north-western Belarus (then the Augustów Voivodeship of the Kingdom of Poland). From the time it was first built, the canal was described by experts as a technological marvel, with numerous sluices contributing to its aesthetic appeal. The completed part of the canal remained an inland waterway of local significance until rendered obsolete by the regional railway network.

3153 POLAND (Podlaskie) / BELARUS (Grodno / Brest) - Białowieża Forest (UNESCO WHS)

The Białowieża Forest World Heritage site, on the border between Poland and Belarus, is one of the last and largest remaining parts of the immense primeval forest that once stretched across the European Plain. Situated on the watershed of the Baltic Sea and Black Sea, this transboundary property is exceptional for the opportunities it offers for biodiversity conservation. It is home to the largest population of the heaviest land animal of the continent, the European bison (Bison bonasus) (almost 25% of the total world's population).
