Westfalenpark is a 70-hectare public park immediately south of the city centre, adjacent to Signal Iduna Park. It was designed as a showcase of postwar urban planning and horticulture and remains one of the best-kept public parks in the Ruhr. The grounds contain rose gardens, a Japanese garden, several small lakes, and a miniature railway that loops through the park's quieter corners.
The Florianturm — the 220-metre TV tower at the park's heart — can be ascended by lift for views across Dortmund and, on clear days, well into the Sauerland hills. The park also contains the Westfalenhallen exhibition centre, which hosts trade fairs, concerts, and sports events year-round. The park is free to enter and open year-round; the tower has a small admission charge.
