Rosengarten der Stadt Köln, Public rose garden in Neustadt-Nord, Cologne, Germany.

This municipal rose garden displays over seventy varieties of contemporary roses, including floribundas and tea hybrids, arranged in organized planting beds with pathways and seating areas for visitors to explore.

Established in 1919 on the site of former Fort X, the garden was designed by architect Fritz Encke after the medieval fortifications were demolished following World War I damage.

The garden holds over 70 rose varieties, mainly modern roses, floribundas and tea hybrids, many bred by Reimer Kordes and W. Kordes' Söhne, among them 'Aachener Dom', 'Duftwolke' and 'Ulmer Münster'. The secluded grounds appear in Heinrich Böll's novel Gruppenbild mit Dame and in Mike Schwarz's crime novel Fort X – Mord im Rosengarten.

Access to the rose garden is only through the Enveloppen Thor of the fortification, which is open during the day only. The pergola-like rose pavilion on the raised northern tip is reached by a few steps. The garden lies on the Neusser Wall in Neustadt-Nord.

The secluded garden in Fort X served as a setting for a scene in Heinrich Böll's novel Group Portrait with Lady, and for Mike Schwarz's Cologne crime novel Fort X – Mord im Rosengarten.
