The Augustów Canal 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. 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.
