Aggersund is a village in northern Denmark with a population of 290 (2022). The village is a part of Vesthimmerland Municipality in the North Jutland Region. Evidence of settlement in Aggersund dates back to the stone age, and the village contains one of the oldest viking fortresses in Denmark, Aggersborg. Much of the village's modern growth is associated with the commerce brought by the village's bridge. The Aggersund bridge () was once one of few crossings on the Limfjord. Because of the bridge's regional importance, it was a location of interest during the German occupation of Denmark and had a heavy occupying military presence during WWII. History There is evidence of a Stone Age settlement near Aggersund, from c. 5000 BCE. The remains of this settlement are located slightly north of the present day village, apparently because the strait of the fjord which it is located on was then significantly wider. During the Iron Age, a larger village emerged on the site. This village was torn down, likely to make room for the grounds of Aggersborg, a viking ring fortress, which was likely erected c. 980. Some archaeologist postulate that the displaced residents of this viking era village resettled in Øster Ørbæk on the southern bank on the fjord. An 11th century estate adjoins the viking ring fortress. It was formed in 1086 as a royal estate, owned by the crown. The original buildings were destroyed by a fire in the 15th century, and were not rebuilt. The estate then briefly became known as Kongensgaard, which retained its rights over Aggersund as a fief. The estate was sold by the crown in 1579 to Vibeke Podebusk, who then constructed a new manor house on the property called Aggersborggaard. The estate's main building was constructed during the 1750s from salvaged architectural elements from several older sites. Several restorations of the property have been carried out since the 20th century. The main building itself was restored in 1936 and rebuilt in 1978. The village was traditionally a part of Hanherred, historically referred to as Hanæhæreth. The herred was an independent fief during the later middle ages, though alternately belonged to the Syssels of Thysyssel and Vendsyssel. In the 1660s, Hanherred was divided between several counties of Denmark: Aalborg County, Aastrup County, Sejlstrup County, and Thisted County. The village of Aggersund became part of Hjørring County in 1793 and constituted the administrative parish
