The Jasna Gora Monastery in Czestochowa, Poland is the most famous shrine to the Virgin Mary in Poland and the country's greatest place of pilgrimage - for many its spiritual capital. The image of Black Madonna of Czestochowa, to which miraculous powers are attributed, is Jasna Gora's most precious treasure. Founded in 1382 by Pauline monks who came from Hungary at the invitation of Wladyslaw, Duke of Opole.
