Steinsberg sits on a wooded hilltop above the village of Weiler, about six kilometres south of Sinsheim. The 31-metre pentagonal keep — unusual for German castle architecture — has been standing since the late twelfth century and is open for a steep climb up wooden stairs to a viewing platform.
From the top, the whole Kraichgau spreads out: vineyards, the Black Forest on a clear day, and the high-rise outline of Heidelberg to the north. The castle courtyard has a restaurant in the old keep buildings, popular with cyclists on the Kraichgau wine route.
