Burg Lichtenfels, Medieval castle ruins in Rottweil, Germany.

Burg Lichtenfels is a ruined hilltop castle above the Glatt valley, on a ridge at about 500 metres between Leinstetten and Bettenhausen, both districts of Dornhan in the Rottweil county. Of the medieval complex, the shield wall survives in full and a section of the south wall in part; the former moat is still traceable around the castle hill.

The castle, first mentioned in the 12th century, was probably founded by the Counts of Hohenberg. It was destroyed for the first time in the Battle of Leinstetten in 1298. In 1423 it was partly owned by the Counts of Zollern. In the 15th century Countess Henriette of Württemberg had Lichtenfels besieged and Count Friedrich of Zollern taken prisoner. The ruined castle was not rebuilt and was abandoned in favour of Leinstetten Castle.

The castle served as a stronghold for the Lichtenfels family and remains a landmark in the surrounding landscape. Walking through the ruins, you can see how this location shaped the region's power structure.

The ruins are open to public access and can be freely explored. The hillside location requires some care when navigating the remains.

The shield wall survives in full, but the south wall only in part; the moat is still traceable around the hill. The ruin passed to the Freiherrn von Podewils at the end of the 20th century and was thoroughly restored, so the surviving masonry stands on consolidated foundations.
