Żupny Castle in Poland's famous saltmine town of Wieliczka, located in the country's southern region of Lesser Poland, is undergoing general renovation in order to make it more accessible for sightseers. During the works, a number of original polychrome wall paintings have been discovered, dating back to the times of the Vasa dynasty. "Here we have beautiful original paintings, which we didn't even know existed," said the director of Cracow Saltworks Museum in Wieliczka, Jan Godłowski.
