Westfalenpark, Public park in Dortmund, Germany.

Westfalenpark is a seventy hectare park with sprawling gardens, walking paths, playgrounds and the two hundred twenty meter tall Florianturm in central Dortmund. The grounds stretch across gently rolling terrain with large lawns, a lake and themed garden sections.

Westfalenpark opened in 1959 for the first of three Bundesgartenschau held in Dortmund, the others following in 1969 and 1991. It was laid out on the grounds of the old Kaiser-Wilhelm-Hain, the Buschmühlenpark, a waste disposal site and overgrown allotments, centred on the 220-metre Florianturm. For the 1969 Euroflor show the park was extended by 10 hectares, adding the Rosarium and the Water Heart.

The German Rosarium within the park displays more than three thousand rose varieties and draws enthusiasts from across the region. The lake stage beside the large pond hosts summer concerts and performances that bring families and visitors together under the open sky.

The park sits at An der Buschmühle three and offers several entrances, restaurants, parking areas and connections to the public transport network. Paths are well accessible and lead through different areas, so visitors can choose routes based on their interests.

The Water Heart in the Rosarium is a basin whose water level changes periodically, not on a published timetable. The Sonnensegel awning that Günter Behnisch designed for the 1969 show proved a self-supporting roof could work, and the Munich Olympic Stadium was built after it.
