The Vikings had a stronghold at Aggersborg surrounded by an enormous rampart. Towering to the north of the rampart there is a church of Aggersborg, probably erected during the 12th century. An interesting illuminated inscription of runes can be seen on the walls of the nave and the northern chancel wall. The altarpiece dates back to 1598, but it wasn't placed in Aggersborg until 1934. The previous altarpiece can be seen on the northern wall of the nave. It pictures the founding of The Lord's Supper. There used to be family burial places behind the beautiful lattice.
References:The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
