Magnificent villas surround the Nero valley, which is laid out in the style of an English landscape park and is home to the Bismarck monument. The formerly natural meadow valley of the Schwarzbach stream was redesigned between 1897 and 1898. Villas from the Romantic and late Historicism, Wilhelminian and Art Nouveau periods line Taunusstraße, which leads to the end of the Nero Valley.

A war memorial was erected there in 1909 for the fallen of the Nassau infantry regiments numbers 87 and 88. At the memorial, one street branches off into the southern and one into the northern Nero Valley. The buildings along these roads were constructed between 1843 and 1888.

The oldest and still existing part of the development is the villa Südliches Nerotal 6, built around 1850. The building originally served as a cold water baths and was used as a residential building from 1874.
