From 1862, the residential buildings were built west of the Gaußberg, which also led to the change in the park. The still existing black pines come from this time. In 1880, the eponymous Gauss monument designed by Schaper was erected at the end point of the Inselwall and surrounded the statue with a wrought-iron lattice. Gauss himself used the mountain for his named after him Gauss-Krüger coordinate system, was measured to the whole of Germany, as evidenced by some old surveying stones on the mountain.
