The Słupia, the Radunia, and the Wierzyca are rivers whose location and energy of water flow was taken advantage of to build hydroelectric power plants. Many of them are still operating and can be visited. The oldest such power plant in Europe, Struga, or the Radunia’s highest-situated plant in Bielkowo, are only a few of the facilities well worth seeing. The principles of physics, chemistry, and mathematics are contained in machines and post-industrial sites, and presented at thematic exhibitions, such as in the Hewelianum Centre.

The gauging station building in Korzeniewo

On an embankment in Korzeniewo a small green house with original architecture, catches the eye.

It is a highly-idiosyncratic gauging station built in the 1940's, when the Prussians conducted water regulation works on the Lower Vistula Valley, building a river harbour in Korzeniewo, and, as part of it, the house, which holds the mechanisms of the gauging station. The little tower, which is still in place, featured a circular recess (now boarded-up). similar to the faces of town-hall clocks. The crews of tugboats and river boats navigating the Vistula could read the water level from far away, as shown by a large hand on the scaled face. The station worked mechanically; the indications changed automatically, depending on the location of a floating indicator in a well inside the house. The well and the harbour basin acted as communicating vessels, thanks to which the floating indicator stayed at the same level as the water in the Vistula. Before World War 2 the gauging station went out of use. Today it is a Roman Catholic chapel.
