Ravensburg, Medieval castle in Sulzfeld, Germany

Ravensburg is a castle on a hilltop east of Sulzfeld with defensive walls, storage buildings, and a central fortified core built across multiple phases. The complex contains several residential houses that show architectural differences from various construction periods.

Building began around 930, but the current structure dates from 1220 to 1222 under Ravan von Wimpfen as a seat for the Sulzfeld family. In later centuries the complex was expanded and renovated multiple times.

The castle's name traces back to the family of Ravan, whose influence shaped the region for centuries. The different houses within the complex reflect changing ownership and how residents lived across different periods.

The castle stands about 1.3 km east of Sulzfeld's centre on a 285.8 m spur, more than 80 m above the Kohlbachtal valley floor, and is surrounded by vineyards on all sides except the northeast. The climb is on foot; the keep is not accessible.

The castle sits at 285.8 metres above sea level on a spur above the Kohlbachtal, more than 80 metres above the valley floor. Vineyards surround it on every side except the northeast. A 17th-century Göler chronicle dates the start of construction to 930 and names a knight Rabanus, now regarded as legend.
