Swedish History Buff Unearths Lost Medieval Monastery Using Old Map and Radar

Swedish archaeologists have made a remarkable discovery, uncovering the remnants of a medieval monastery in Derome, thanks to the research of a history enthusiast. The site was found by Göran Bengtsson, a dedicated hobbyist who noticed a mysterious symbol on an old map. The symbol, a rectangle marked as ‘Klosterkullen’ or ‘monastery hill’ on a 1760 map, guided the archaeologists to the location.

Arkeologerna, an archaeological organization associated with the Swedish government, announced this month that the monastery ruins were found in a field in Derome, a town in southwest Sweden. Bengtsson’s insight led to the use of ground-penetrating radar (GPR) technology to investigate the site further. The GPR revealed the walls of what are believed to be monastery ruins, offering a fascinating glimpse into Sweden’s medieval past.

Archaeologist Bengt Westergaard, who has spent 40 years in the field, described the discovery as unique. He expressed that the visibility of the walls was particularly striking. The dry summer conditions played a role in making the structures clearly visible, with the ground showing crop marks that made the walls stand out.

The site features walls that are nearly 6.5 feet thick, with some indicating the remains of pillar foundations. Experts believe the site might have been the original location of the Cistercian Ås Abbey, which was later moved in the 13th century. The monastery’s history could provide valuable insights into Sweden’s religious and cultural heritage.

Sweden, known for its rich history, has witnessed several archaeological discoveries in recent years. Last spring, archaeologists unearthed a 12th-century grave and found buried treasure. This year, Arkeologerna also announced the discovery of a ‘Viking-era’ coffin with Christian overtones, which has puzzled experts. These findings underscore the country’s significant role in uncovering its medieval past, offering a deeper understanding of its historical landscape.
