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.
