[1] Aalborg was already a town in the mid-10th century, with a fine position on the east-west Limfjord that served as a trade route between the North Sea and the Baltic until the 12th century, when the west end of Limfjord was closed by sand drifts.

The Lindholm Høje at Nørresundby across the Limfjord features a notable Viking Age burial site indicating that this was a populated area of Denmark long before the town appeared on the fjord.

In the crypt of Budofi Cathedral visitors can see the remains of the large stones used for the original church that was built at the direction of Bishop Eskil of Viborg no later than 1132.

[2][3] The church was constructed in the Gothic style out of Denmark's most common building material, large bricks.

The abrupt truce with Lübeck freed up royal troops who chased the peasants back to the walls of Aalborg.

The royalist troops stormed the gates and commenced the sack and bloody slaughter of the rebels and citizens of the town.

By 1800 the Abbey Church and tower were dismantled, and the stone was used to expand nearby Aalborg Castle (Danish: Aalborghus).

The square 28-metre-high (92-foot) brick tower is topped with a 35-metre (115-foot) metallic Baroque cupola and spire.

The main altar piece was added in 1684, a gift of Niels Jespersen and his wife Margareta Erichsdatter.

The black and white marble baptismal font was given to the church in 1728, a gift of the widow Maren Grotum Von Pentz.

The pulpit (1692) was a gift from the first apothecary at Jens Bang's House in Aalborg, Johannes Friedenreich and his wife, Magdalena Calow.

The epitaphs for Jacob and Elizabeth Himmerig in 1773 and 1774 are examples of neo-classical design and commemorate the church's greatest benefactors.
