Small hydropower plant in Słowik
Construction in a direct conservation protection zone
The small hydropower plant in Zagrody, also called the small hydropower plant in Słowik due to its location, was built first in the buffer zone of the Chęcińsko-Kielce Protected Landscape Area and then in the immediate vicinity of a technical monument, a water mill complex in Markowizna. The buildings of the small hydropower plant have been adapted to the existing, historic buildings to create an aesthetic whole.

The mill building, next to which the small hydropower plant is located, is an old historic facility. In the old days, Marek's Mill (in Markowizna, then Słowik) was one of a lot of facilities using the extremely efficient river Bobrza. In addition to buildings from the past centuries, a hydrotechnical system with a weir and a mill race remained. Currently, a fish pass has also been added.
