Rosarium, Westfalenpark, Rose garden in Dortmund, Germany

The Rosarium in Westfalenpark is a specialized facility that displays thousands of rose varieties organized in dedicated sections, ranging from classical heritage roses to modern breeding lines. The layout is divided into thematic areas where visitors can learn about different rose types and their distinctive characteristics.

The facility was founded in 1972 following an agreement between the German Rose Friends Society and Dortmund city authorities. The project expanded an older rose garden area with new sections, transforming it into the substantial collection that exists today.

The garden serves as a gathering place for rose enthusiasts and gardeners worldwide who visit to observe rare varieties and exchange cultivation knowledge. People use the different sections to find inspiration for their own gardens or simply spend time surrounded by roses.

The garden is easy to explore on foot, with marked pathways and signage that makes navigation between the different rose sections straightforward. The best time to visit is during the blooming season, when most varieties flower simultaneously and the full beauty of the collection is on display.

The rose library holds 1,800 specialist books, making it one of the largest collections on the subject worldwide. The two source editions give different figures, 1,800 and 1,300 volumes, so the count is disputed. The garden itself is laid out along a rose path with 38 stations, and a climbing rose wall 65 metres wide and 6 metres high runs through it.
