[4] Weyhe visited the site twice per year to inspect the work, to determine trails and the lake with an island, a bridge and the Bastei which remains.

The building within the park were designed by architect Adolf von Vagedes [de], who continued Reinking's after his death in 1819, and te Stroet.

[2] With city planning director Richard Nose, it was enhanced by a small herb garden.

[2] In 1945, shortly before the end of the war, officers of the Gestapo murdered almost 300 people in the Rombergpark and the nearby forest Stadtwald Bittermark [de].

The victims were mostly forced labourers and prisoners of war from several European countries, as well as previously imprisoned opponents of the Nazi regime.

[2] Today the garden contains a historic English landscape park with monuments, an arboretum containing thousands of species of woody plants, including some of the largest trees of some species in North Rhine-Westphalia, a terrace with palm trees, and four greenhouses with a total area of 1000 m2[1] for cactus and succulents, ferns, tropical plants, and camellias, jasmine, and lemons.
