Gråborg

Gråborg is the ruin of a hillfort on Öland, Sweden. It is located in Algutsrum, in Mörbylånga Municipality. The oldest parts of the ancient hillfort are plausible from the 5th century. The hillfort was expanded in stages into the 12th century. During the Middle Ages, Gråborg was probably utilized as a protected marketplace.

Gråborg was for a long time Öland's largest known ancient hillfort. In 2021, Sörby borg was discovered in central Öland, which is larger.

Gråborg consists of a circular rampart, approximately 4 meters (13 foot) high. On the outside, the stones are partly in mortar, which means that the wall has been preserved quite well over time. Gråborg has three openings, one of which has been equipped with a tower superstructure, which was constructed during the Middle Ages. No remains of houses or other buildings have been found inside the hillfort itself due to the land's previous role as agriculture field which destroyed all visible traces of house foundations. However, the size of the hillfort shows that it was a central point in ancient times, perhaps a trading post. Older names of the hillfort are "Backaborg" or "Borg".
