Swedish archaeologists have discovered a significant structure from the pre-Viking era

Gamla Uppsala (Old Uppsala)

Stockholm - Swedish archaeologists have unearthed remnants of unusually large wooden artifacts from a period even before the Viking era. They were aided in this discovery by excavation work ahead of a planned railway construction.
The workers stumbled upon two rows of wooden pillars in Old Uppsala, which is known as an ancient religious center of the former pagans. One colonnade is one kilometer long, and the other is half that length.
Archaeologist Lena Beronius-Jorpeland told the Associated Press that the colonnades probably originated in the 5th century. The reason for their construction remains unclear. According to her, this is the largest and most complexly planned structure from this period discovered in Sweden.
Beronius-Jorpeland specified that the pillars measure at least seven meters. They were positioned six meters apart in a row. The bones found near them suggest that animals were sacrificed there according to pagan customs during their construction.
