UNESCO World Heritage

King Harald Bluetooth's five ring fortresses Aggersborg, Borgring, Fyrkat, Nonnebakken and Trelleborg were on 17 September 2023 included in UNESCO's distinguished list of places of exceptional value for all humanity.

With the ring fortresses, there are now 11 areas on the UNESCO list for Denmark and the Commonwealth. Being designated as a World Heritage site is a blue stamp of a site's global importance and obligates to protect, preserve and spread knowledge of the site.

Aggersborggaard

With a history that goes all the way back to the Viking Age, Aggersborggaard is one of the country's oldest manors.

Aggersborg Church

The construction of the church began in the 12th century and ended no later than the 13th century. It appears in hewn stone blocks, which are characteristic of Vesthimmerland's Romanesque village churches.
