The Killesbergpark (Höhenpark Killesberg) is an urban public park of half a square kilometre (123 acres) in Stuttgart, Germany. It is just north of the state capital, where Killesberg is a quarter of the borough of Stuttgart-Nord (North).
The park dates back to the horticultural show of 1939. Before the show, a large area of the park had been a quarry. It was transformed into a park with exhibition sites for the show, and has remained, hosting horticultural events on a regular basis, including the “Bundesgartenschau” and the IGA (Internationale Gartenbauausstellung), both garden festivals.
The Killesbergpark bordered for many years the city's fairgrounds. In 2007, Messe Stuttgart moved to new ground close to Stuttgart Airport.
Every July the park hosts the popular Lichterfest Stuttgart. Thousands of lanterns are placed around the park, decorating the park for a variety of family activities throughout. After dark, there is a fireworks show accompanied by music. Visitors often bring blankets to sit on for the show.
Since its opening, the park has been home to the 381-millimetre (15-inch) narrow-gauge Killesberg railway. In the summer months, visitors can see two diesel and two steam locomotives, which have been fixtures in the park since 1950. The horticultural show of 1939 saw the opening of the railway, when two borrowed steam engines from Leipzig traversed a short stretch of track. During World War II, the steam engines were returned to Leipzig for use there. New locomotives were purchased, and today there are two diesel and three steam engines in use.
Completed in 2000 the Killesberg tower is an observation tower, 40m high overlooking the park. It is cable-stayed tower construction designed by Jörg Schlaich, using cable-stayed bridge technology.
