About
Borgring, also known as Vallø Borgring, is a Viking ring fortress located near Køge on the island of Zealand, Denmark. Built around 970 CE, it is a circular structure with a diameter of 145 meters. The fortress features a significant rampart, 10-11 meters wide, and a protective palisade made from pointed wooden stakes. While no artificial moats have been discovered, natural water features such as the nearby Ellebækken stream and a small lake might have served defensive purposes. Borgring is part of a group of Viking fortresses, including Trelleborg, Nonnebakken, Fyrkat, and Aggersborg, believed to have been constructed under the reign of Harald Bluetooth. The site highlights the strategic and military prowess of the Vikings during the Early Post-Classical Period.
