The Poland-Germany border is a 467-kilometer-long boundary that separates Poland from Germany. It runs from the Baltic Sea in the north to the Czech Republic in the south, following the course of the Oder and Neisse rivers for a significant portion. This border has historical significance, having changed multiple times over the centuries due to various conflicts and treaties. Today, the border is an important part of the European Union and is characterized by open crossings, allowing for the free movement of people and goods. It plays a vital role in trade and cultural exchange between the two countries, fostering cooperation and mutual development.
