The park, which begins at the end of Taunusstrasse and ends after just under a kilometer at the Nerobergbahn viaduct, was laid out between 1897 and 1898. After its completion, almost 6,000 plants from all over the world adorned the six-hectare park, which was therefore often referred to as a "botanical garden".

The Nero Valley park, which is shaped by the course of the Schwarzbach stream and has been a listed building since 1985, is home to the war memorial completed in 1909 and a Bismarck memorial created in 1898. Lined with magnificent villas, the Nero Valley with its ponds and artistically designed bridges is a popular local recreation destination for Wiesbaden residents and visitors to the city.
