At the end of the 1990s, the attention of the Hildegard researchers was drawn to the village Niederhosenbach near Kirn, counting a little more than 300 inhabitants. Josef Heinzelmann at this time brought the tiny place into the mystery about Hildegard of Bingen’s place of birth. In a certificate from the monastery on the Disibodenberg of 1112, he discovered the name Hildebrecht de Hosebach, who he considered Hildegard’s father. He assumed that, where the church stands today, there was once the castle of the gentlemen of Hosenbach. In 2002, a memorial plaque was put on the church that announces: „At this altitude there was once the residence of the noble gentlemen of Hosenbach. (…) It can be assumed that she (Hildegard) was born here, at the residence of her parents in the former „Hosebach“.“ Every other year, the medieval Hildebrecht Market takes place here and the „spirit“ of a night watchman, which the priest transforms into on some nights, tells stories from Hildegard’s time.
