Hohenrode Park is the largest historical park in Nordhausen.
In the 19th century, the Nordhausen chewing tobacco manufacturer Carl Kneiff commissioned the construction of the villa now named after him and its surrounding green spaces. The famous architect Ludwig Bohnstedt and the landscape gardener Heinrich Siesmayer designed the park. Following the style of English landscape gardens, Siesmayer mainly planted indigenous trees such as maple, lime, elm and oak, as well as some red-leaved, white-flowered horse chestnuts and trumpet trees near the striking villa. Carl and, later, his son Fritz Kneiff were enthusiastic collectors of trees and shrubs. They gradually extended and enriched the park and so numerous rare woody plants were added. Today, the freely accessible Hohenrode Park is the only Siesmayer Park to have been preserved in its original form and not built over. For a number of years now, a civic foundation and a support association have been successfully involved in preserving the 140-year-old historic park and in renovating the Kneiff Villa and other buildings such as the charming Kutscherhaus (coachman's house), which today is home to a café, or the classicist garden pavilion. Park Hohenrode is an outdoor location for the Bundesgartenschau 2021 (Federal Garden Show) in Erfurt.
