Sandby borg is an Iron Age ringfort, one of at least 15 on the island of Öland, Sweden. It sits about 2 kilometers southeast of Södra Sandby village in Sandby parish in southeastern Öland. It is close to the village of Gårdby.
From 2011, the fort has been the subject of excavations, the results of which show that it was the scene of a massacre in the late fifth century AD. The victims of the massacre were never buried, but are found lying as they fell, inside the houses and scattered on the streets of the fort. This has resulted in a unique snapshot-characteristic of the archaeology at Sandby borg, providing new insights both to violence and conflict in the Iron Age, and concerning everyday life in the ringfort.
