Bårby borg, Iron Age fortress near Bårby, Sweden.

Bårby borg is an Iron Age fortress located near the small community of Bårby in Sweden. The settlement covers roughly 150 meters across and features a semicircular stone wall positioned along a natural limestone cliff edge.

The fortress was first built during the Migration Period in the 5th century and later reoccupied during medieval times. Two distinct phases of settlement mark the history of this location.

The objects found here show what mattered to people in different eras and how they lived their daily lives. Clothing items, eating utensils, and decorated pottery reveal personal stories of inhabitants.

The site is easily accessible with parking available directly adjacent to the fortress and an entrance marked near an information board. Visitors can walk around freely to examine the stone structures and the cliff features.

Among the finds were dress clasps, knives, combs and pottery, but the most notable is a gold coin struck for the Byzantine emperor Justin I, who ruled from 518 to 527. It is the only coin of its kind found on Öland's fortresses.
