The Trail of the Eagles' Nests of south-western Poland, is a marked trail along a chain of 25 medieval castles between Częstochowa and Kraków. The Trail of the Eagles' Nests was first marked by Kazimierz Sosnowski. Since 1980, much of the area has been designated a protected area known as the Eagle Nests Landscape Park.

However, Częstochowa is historically part of the Lesser Poland region, not of Silesia, and before 1795, it belonged to the Kraków Voivodeship. Częstochowa is located in the Kraków-Częstochowa Upland. It is the largest economic, cultural and administrative hub in the northern part of the Silesian Voivodeship.
