Botanischer Garten Rombergpark, Botanical garden with English landscaping in Dortmund, Germany.

Rombergpark is a landscape garden in Dortmund that covers 68 hectares and brings together woody plants from temperate climates alongside greenhouses for tropical and subtropical species. The paths lead through different zones, from open meadows to dense tree plantings, while the glasshouses provide controlled environments for delicate species.

The Romberg family had their Brünninghausen estate redesigned as an English landscape garden between 1817 and 1824, following the Classicist remodeling of the house by August Reinking. The plan was drawn up from 1818 by Düsseldorf court gardener Maximilian Friedrich Weyhe, and the design is kept in the Landesarchiv NRW. Dortmund bought the property in 1926 and moved its botanical garden there; from 1950 Gerd Krüssmann rebuilt it as an arboretum.

The park's name comes from the von Romberg family, who owned the Brünninghausen estate until the city bought it in 1926. A linden alley planted in 1888 still lines a path, and the annual rhododendron bloom draws visitors. Near the north entrance, a memorial stone with white roses commemorates the victims of Gestapo executions carried out in the park in 1945.

The outdoor grounds remain open around the clock, while the glasshouses follow fixed hours and work well for visits on rainy days. Guided walks take place regularly and offer insight into plant diversity without requiring prior knowledge.

The collection holds roughly 4,500 species of woody plants, making it one of the largest in Europe, though many visitors barely notice the scale because the plantings blend into the landscape design. The garden functions as both a place for walking and a research site, with both roles coexisting without interfering with each other.
