One theory is that Gorm died in the winter of 958–959; this is based on
dendrochronology that shows that the burial chamber in the northern burial mound in Jelling was made from wood felled in 958.
Arild Huitfeldt relates one legend of his death in
Danmarks Riges Krønike: This account would contradict information on the Jelling Stones which point to Queen Thyra dying before Gorm. Some
archaeologists and
historians have suggested that Gorm was buried first in Queen Thyra's grave mound at Jelling, and later moved by his son, Harald Bluetooth, into the original wooden church in Jelling. According to this theory it is believed that the skeleton found at the site of the first Christian church of Jelling is in fact Gorm the Old, though the theory is still much debated. During the reign of Gorm, most Danes still worshipped the
Norse gods, but during the reign of Gorm's son, Harald Bluetooth, Denmark officially
converted to Christianity. Harald, accordingly, left the hill where Gorm had originally been interred as a memorial. == Legacy ==
