Concurrently, in the 15th century an adjacent tower, a so-called kastal [sv] was erected nearby, likely serving a defensive function.

During the same century, the interior of the church underwent alterations, with new vaults constructed, possibly decorated with murals initially.

All the church walls were heightened, with the new sections constructed of brick, and crow-stepped gables were added to the tower and kastal.

[1][3][5] Another 12th-century object originally from Löderup Church is a decorated burial monument, depicting lions and human figures on the slab.

Legend holds that it was destroyed by the men of Jens Grim, a knight and member of the Council of the Realm, who had been excommunicated by the priest of Löderup Church for having pillaged the parish.

It carries the coat of arms of king Christian IV of Denmark and queen Anne Catherine of Brandenburg (the province of Skåne only became Swedish in 1658 following the Treaty of Roskilde).
