Gråborg: A massive hillfort shrouded in mystery

Gråborg, a towering hillfort of Öland dating back to the 5th century, expanded over centuries up to the 12th. Though it's suggested that Gråborg might have served as a protected marketplace during the Middle Ages, the true purpose and the intriguing tales behind its names, 'Backaborg' or 'Borg', remain unresolved mysteries. Today, Gråborg’s interior lies beneath vegetation, with only three openings surviving, one of which features a tower structure.

Archaeological findings from Gråborg, including the original names of artifacts, are now at the Kalmar County Museum. A short distance away, you'll find the ruins of St. Knut’s Chapel, built in the 12th century but abandoned in the 16th. In 1560, the chapel’s single bell was taken by the crown. The altarpiece from the chapel, crafted in 1475, can now be found in Algutsrum Church, featuring Christ crowned with thorns flanked by Saint Birgitta and Saint King Saint Canute. The altarpiece, placed centrally, depicts Saint Eric and Saint Olaf on the left door, and Saint Henry and Saint George on the right.

Remains of a small cemetery are situated nearby, containing both skeletons and gravestones.
