On a cape in Oxhultasjön lie the remains of Sjöboholm Manor with roots from the Middle Ages. In the 1400s and much of the 1500s it was the home-farm for the county of Itzholte, the Danish Bergslagen at that time, with rich resources of bog ore and bog iron ore. Christian IV of Denmark supposedly stayed at Sjöboholm during one of his travels to meet the Swedish king Gustav II Adolf. The Scanian noblewoman Gertrud Grip bought the farm in 1647 and two years later she got married there to Göran Galle. Around 1840 the farm was abandoned, and now only the ruins remain on two islets. The place is well looked after, and it is easy to find a nice spot for a picnic.
