Within the present-day Danish realm, we know of five ring castles from the time of Harald Bluetooth. At Fyrkat, an earthwork marks the site of the castle, and right next to it is a reconstructed longhouse. The Viking farm at Fyrkat consists of nine reconstructed houses from a manor house from the time of Harald Bluetooth. On selected days in spring and summer, there are lively workshops and activities here. https://nordjyskemuseer.dk/de/u/vikingemuseet-fyrkat-de/

Experience the Viking Age first hand at Fyrkat, one of Denmark's five ring castles. Fyrkat Castle was built in 980 under King Harald Bluetooth. None of the original ring castles still exist today, but at Fyrkat an earthen rampart marks the place where the ring castle surrounded the original 16 longhouses. The position of the houses is now marked with white stones. Just outside the castle, one of the longhouses has been reconstructed. In the immediate vicinity of Fyrkat Castle is the Viking settlement, which consists of nine reconstructed houses. Together, these form a manor house as we know it from Harald Bluetooth's time. Both houses and workshops, including the smithy, are built of oak and have clay-plastered walls and thatched roofs. During the summer, there are activities on selected days at the Viking settlement, where you will also find a visitor center, a museum shop and a mythological playground. Fyrkat is on the UNESCO list of intangible world heritage sites, along with the four other Danish ring castles – Aggersborg, Borgring, Nonnebakken and Trelleborg. https://nordjyskemuseer.dk/de/u/vikingemuseet-fyrkat-de/
