On the history of the farm that gave Hochdahl its name:
Gut Hochdahl - first named after the nearby train station in 1841, then named after the local settlement (previously called "Millrath") or today's Erkrath district in 1938 - was demolished in 1969 by the Hochdahl development company. The aim was to found a "new" city on Hochdahler Boden in order to relieve the city of Düsseldorf.
First mentioned in a document in the 1300s, historical documents from the past centuries contain many spellings and names ("dat goit ym daill", "dat guyt ym dail", "der Dall", "Hohendal") for the then Hochdahl treasure trove, which has had several owners over its more than 600-year history: When it was sold in 1494 by the van and zu Oersbeck and zu Kentenich families to the brotherhood of “Our Dear Women”, the estate initially became a church property. In 1803 the estate passed into the possession of the Gruiten family Birschel, who were closely connected with limestone mining. From the 1870s onwards, the estate was owned by the Spiecker family until it was sold to the Hochdahl development company.
