The church's north wall is its most remarkable feature: a largely untouched limestone facade dating from the first half of the 1100s, complete with a Romanesque doorway and window. For centuries the whole building was thought to date from 1598, until research by theologian Curt Wallin in the early 1950s revealed that the foundation stones of the north wall differed in shape from the rest. Subsequent uncovering of the wall confirmed its medieval origin, making it one of the older surviving fragments of Skåne church architecture still visible today.
The rest of the church, including the south side and chancel, was rebuilt in 1598 as a burial church for the lords of the castle, complete with a burial vault. The pews from this period survive, with the Brahe family's coat of arms on the men's side and the Pasberg arms on the women's side, reflecting the church's close ties to the aristocratic families of Tosterup.
Inside, visitors can see striking wall paintings from the 1400s, attributed to the so-called Vittskövle Master, sometimes identified as the medieval church painter Nils Håkansson of Vadstena. These paintings were created in the spirit of Saint Bridget, who is depicted at her writing desk in the place of honour on the triumphal arch. The chancel holds a depiction of the legend of Saint George and the dragon, while a scene showing the Mass of Bolsena appears on the east wall of the nave, beside the triumphal arch.
The porch contains the ornate coffin of Jörgen Krabbe, a notable feature for visitors, and sources also mention a gravestone commemorating Tycho Brahe the Elder, said to have been made by the sculptor Adam van Düren, though this attribution is not independently confirmed here. The church is also mentioned in Fritiof Nilsson's novel Bombi Bitt och jag, adding a literary footnote to its history.
The furnishings from the 1700s, including much of the church's fittings, complete the interior's layered character, blending Romanesque stonework, Renaissance-era rebuilding, and later decorative additions into a small but memorable castle church.
