Sand alluvia on the entire width of a river are one of the marks of a braided river, natural and untamed.

The Vistula river


The history of the Vistula in Warsaw area goes back several thousand years ago, when there was a big post-glacial loam reservoir. Novadays no one things about river in such categories.

The climate warming caused the retreat of ice, releasing the water flow. Currents appeared in the stagnant lake. Cyclical processes of stagnation and water flow – resulting in alternating sediment accumulation and erosion – shaped subsequent horizontal river-terraces in the valley of Vistula. Three higher levels of terraces have been formed during the final stages of the last glaciation, and the lowest floodplain came into being already in the Holocene epoch.

The commemorative celebration of the W Hour, the hour when the Warsaw Uprising started in 1944, takes place also on the river. In that very moment, the entire city comes to a halt: public transport, cars and people stay still for one minute to pay their respect to the heroes of the uprising.

The left bank of the river is a leisure area combined with well-preserved natural environment. Are there any other big cities where nature has been kept as it used to be to such an extent?

The river and its islands are one of the ecological routes Natura 2000. The islands are home to many species of birds. In the picture you can see a few hundreds of cormorants.

Reserves of the darkness.

The problem of light pollution is a civilization problem especially acute in large cities and urbanized areas, for example in Warsaw. In Poland, the first reserves of darkness (for example the Park of the Dark Sky in the Izerskie Montains) came into existence. In urban enclaves such a role is played by Vistula river, parks and urban forests.
