Polish researchers produced a facial reconstruction of a female skull that belonged to an individual buried within a crypt of Yaroslav I the Wise, Grand Prince of Kievan Rus’. The woman is believed to be the second wife of the ruler, Ingegerd Olofsdotter of Sweden.
A double burial was discovered within the ringfort in Czermno, East Poland. It belongs to a beheaded 30-year old male and a few-years-old child. The Czermno ringfort was supposedly known as Czerwień, being the the main keep of so called called Cherven Cities – a state that was fought over by the kings of the Piast dynasty against rulers of Kievan Rus. The graves discovered are dated to 12th-13th century, the time when the Cities were under Rus’ influence.
