Built around 1863,[1] Hinterkaifeck (the prefix hinter, which is part of many German place names, means behind) was never an official place name nor a separate district with this name, but only an unofficial house name. Nearby Kaifeck is an Einödhof, or single farm settlement, located just over 1 kilometre (0.62 mi) to the south of the "murder farm" on the municipal road to Schrobenhausen. The farm, however, did not belong to Kaifeck, but to the village of Gröbern as house number 27 ½ of the municipality Wangen, and was incorporated into Waidhofen in 1971.[citation needed]
