Overview
At Elingaard Manor in Onsøy, just outside Fredrikstad, a centuries-old legend continues to draw curiosity long after the death of its most famous resident, Birgitte Kaas. Known in local tradition as a powerful and uncompromising ruler of the estate, Kaas is said to still haunt the manor house she once controlled “with an iron fist.” Visitors and locals alike have long reported eerie sensations at the property, including strange sounds, fleeting shadows and, most famously, the scent of a heavy, sweet perfume drifting through empty rooms.
The manor’s ghost story is woven into a broader history of fire, rebuilding and aristocratic power. Elingaard is an old estate site with cultural monuments dating back to the Bronze Age, and the buildings there have burned multiple times. A major fire in 1645 destroyed the farm’s structures, household goods, movable property and archives, while another fire in 1746 led to the construction of the current main building in 1749. The house that stands today, with its original basement preserved from before the 1645 blaze, was once one of the largest residences in Norway, underscoring the estate’s importance in regional history.
The Legend of Birgitte Kaas
Birgitte Christine Kaas Huitfeldt was born at Elingaard on 2 October 1682, the daughter of Stiftamtmann Hans Kaas and Sophie Amalie Bielke. Through her maternal lineage in the Bjelke family, she belonged to one of the prominent noble houses of the era. Over time, local storytelling has transformed her into a commanding figure who still presides over the manor from beyond the grave. According to the legend, the house’s ghost is not a vague apparition, but the lingering presence of a woman so attached to her home that she never truly left it.
The folklore surrounding Kaas goes beyond ordinary haunted-house tropes. In the version repeated by the manor’s storytellers, visitors are advised to set an extra plate in case the ghost wants a seat at the table. That detail reflects the way the legend has become part of the estate’s identity, especially since Elingaard is now used for weddings, parties and gatherings. The story is less about fear than atmosphere: a reminder that the old manor is still viewed as a place where the past feels close at hand.
Mystery and Reputation
The most intriguing part of the legend is the question of what may have happened to Birgitte Kaas after her disappearance from the historical record. The source material points to whispers that she may have made a deal with the devil, a detail that gives the story a darker, more supernatural edge. As with many such tales, there is no clear evidence to support the rumor, but the persistence of the claim suggests how deeply the manor’s reputation has settled into local memory.
Today, Elingaard functions as both a museum and event venue, and during the summer season it is open to the public. That dual role makes it a fitting setting for a ghost story: a historic home where archival history, noble lineage and oral tradition coexist. Whether Birgitte Kaas’s presence is best understood as folklore, cultural memory or something more mysterious, the legend continues to shape how people experience the manor. For many visitors, the perfume in the hallways and the stories of a stern noblewoman are now inseparable parts of Elingaard’s enduring identity.
