The Eagles' Nests castles (Orle Gniazda), many of which survived only in the form of picturesque ruins, are perched high on the tallest rocks between Częstochowa and the former Polish capital Kraków. The castles were built to protect Kraków as well as important trading routes against the foreign invaders. Later, the castles passed on into the hands of various Polish aristocratic families.
