In that part of Neandertal, which is located in Erkrath, in the summer of 1856, quarry workers discovered the fossilised remains of what became known as the Neanderthal man or Homo Neanderthalensis in Feldhof cave. The name Erkrath was first mentioned in 1148. Erkrath received town rights in 1966. In 1975, the municipality of Hochdahl was incorporated into Erkrath. As well its former borough Unterbach was incorporated into Düsseldorf. Only a part of Unterbach called Unterfeldhaus remained as now a borough of its own with Erkrath. Erkrath today has three local parts: Erkrath, Hochdahl and Unterfeldhaus.
