Lusatian Nysa, Border river between Czech Republic and Poland.
The Lusatian Nysa is a river forming the border between the Czech Republic and Poland, stretching about 254 kilometers from source to mouth. It flows northward from the Jizera Mountains until it joins the Oder River.
After World War II, the Potsdam Agreement established this river as the boundary between Germany and Poland. This decision reshaped the political landscape of the region for generations to follow.
The river marks a boundary that has shaped how communities on each side developed differently over time. Today, locals on both banks share similar connections to the water through recreation and daily life.
The river is accessible at various points along walking paths and bridges that invite exploration and strolls. The best time to visit is during warmer months when water levels are stable and the surrounding landscape is most active.
The Mšeno reservoir, built between 1906 and 1910, uses underground tunnels to collect water from two different source branches. This engineering solution reveals how early developers harnessed the water resources of the region.
