Roman Catholic Cathedral of the Blessed Virgin Mary of Masovia in Płock
Płock is a town on the Vistula River in the western part of the Masovian Voivodeship. During the reigns of Vladislaus Herman and Boleslaus the Wrymouth in the 10th–11th centuries, Płock was briefly Poland's capital city, and later served as one of the seats of the dukes of Masovia. The town has two cathedrals: the Roman Catholic Cathedral of the Blessed Virgin Mary of Masovia (pictured) where Vladislaus and Boleslaus are buried, and the Temple of Mercy and Charity, the principal seat of the Mariavite Church, a native Polish branch of Christianity. Płock is home to Poland's largest oil refinery, owned by PKN Orlen and served by the Druzhba ("Friendship") pipeline linking Russia with Germany. (Full article...)
