Reign

During his reign, Harald oversaw the reconstruction of the Jelling runic stones, and numerous other public works. The most famous is fortifying the fortress of Aros (nowadays Aarhus) which was situated in a central position in his kingdom in the year 979. Some believe these projects were a way for him to consolidate economic and military control of his country and the main city. Ring forts were built in five strategic locations with Aarhus perfectly in the middle:

, had died in 958, and had been buried in a mound with many goods, after the pagan practice. The mound itself was from c. 500 BCE, but Harald had it built higher over his father's grave, and added a second mound to the south. Mound-building was a newly revived custom in the 10th century, perceivably as an "appeal to old traditions in the face of Christian customs spreading from Denmark's southern neighbors, the Germans." After his conversion, around the 960s, Harald had his father's body reburied in the church next to the now empty mound. He had the Jelling stones erected to honour his parents. The ''
