Nyamiha River, Underground river in central Minsk, Belarus.
The Nyamiha River is an underground waterway running roughly 4.5 kilometers beneath Minsk's streets through concrete channels. It joins the Svislach River and serves as part of the city's modern drainage infrastructure.
A major battle took place along this river in 1067 between forces from Kievan Rus and the Polatsk princedom. Between 1926 and 1955, urban expansion led to the river being channeled underground and incorporated into the city's drainage system.
The river held significance in medieval chronicles and was part of daily life before urban development buried it underground. Locals today occasionally catch glimpses of its remnants through grates and maintenance points across the city.
The river flows beneath the city center, making it difficult to observe from street level, though information panels mark certain public locations. Visiting a local museum provides better context about the city's hidden waterway and how it was developed underground.
Its name comes from a Lithuanian term meaning 'the river that does not sleep', referencing its perpetual underground flow. This old name carries memory of when the waterway ran openly above ground and people witnessed it daily.
