Old Uppsala was a religious center in the ancient Norse religion and later in Christianity, being the seat of the archbishop of Sweden until 1273 (when it was moved to the Uppsala Cathedral). It is a site of multiple burial mounds, including three large “royal mounds”, dating to 5th and 6th centuries (the Vendel period), which form the main features of the site today.
