Aggersborggaard
With a history that goes all the way back to the Viking Age, Aggersborggaard is one of the country's oldest manors. The continuity is emphasized by the fact that today the barn of Aggersborggård occupies the southernmost portion of the fortress rampart and ditch. In the 970s, Harald Bluetooth/Gormsson built the largest of a total of five Danish ring fortresses on the site, which until 1579 was royal property. The Viking fortress was only in use for 10-20 years, but from written sources it is known that King Canute the Holy in 1086 had a royal estate at Aggersborg, as it tells of a revolt against the king, who fled across the fjord, while many of his men were killed at Aggersborg.
Aggersborg is later mentioned in King Valdemar's Land Register from the first half of the 13th century and later in 1272, where King Erik Klipping stayed on the site and issued a still preserved diploma, which exempted Øm Monastery from certain services and taxes. In King Valdemar Atterdag's time, Aggersborg is mentioned again, as Niels Eriksen Gyldenstjerne was commanded by the king to rebuild the fortress, which was burned down by a Jutland nobility revolt in probably 1368/1369. Probably the same fortress, which was found in 2009 in connection with the project "The King's Fortresses".
Aggersborggaard is privately owned by and there is no public access.
Aggersborg Church
During restoration work in the 1970s, several smaller runic inscriptions appeared, including the name Maria. Possibly the church was dedicated to the Virgin Mary. An exposed limestone-carving in the north wall translates to: "God... Thorlek from Hæra. Stand there! Peter S (val) e wrote me. Amen." The runes are dated to the period 1150-1536.
