One River, Many Borders — Europe · Danube Basin
多瑙河流域由 19 个国家共享，约 7,900 万人生活其间。地形让它成为中欧到东南欧的通道，政治又把通道变成渡口、首都与边境的链条。
多瑙河在“铁门”穿过山地，又向黑海展开。它提醒我们：河流可以连接文化，却不必抹去边界。
The Danube basin is shared by 19 countries and about 79 million people. Terrain made it a corridor across central and southeastern Europe, but politics turned that corridor into a chain of crossings, capitals and frontiers.
The river cuts through mountains at the Iron Gates, then spreads toward the Black Sea. It is a reminder that a river can connect cultures without erasing their borders.
