Burg Nebra, Medieval castle ruins in Nebra, Germany

Burg Nebra is a castle ruin located on a hill in central Germany, with several distinct structural remains. The site preserves a residential tower, fragments of a chapel, and vaulted wine cellar spaces positioned at approximately 148 meters in elevation.

The fortress was first documented in 1207 and served as a residence for the Landgraves of Thuringia until 1247, when the Counts of Querfurt took control. Swedish forces occupied the site during the Thirty Years War, leading to its gradual decline and eventual ruin.

The name Nebra is shared with the town below, and the castle site sits on a branch of the old Kupferstraße, the copper road. The Altenburg on the northern spur is regarded as the starting point for the town's development. Since 1969 an open-air swimming pool has occupied the Altenburg grounds, so bathers today use the same spur as the 9th-century fortified settlement.

Burg Nebra lies on a sandstone rock south of Nebra's old town, at 148 m above sea level; the Altenburg spur north of town is a separate site and now holds an outdoor pool opened in 1969. Of the new castle only the residential tower, chapel remains and barrel-vaulted wine cellar survive, so the grounds are visited on foot around these ruins.

In 1962, excavations on the northern edge of today's town, on the site of the earlier Altenburg spur, uncovered the Nebra figurines alongside many other finds. The Upper Paleolithic camp there shows the spur was used long before the 9th-century fortified settlement was built.
