Arboretum Park Härle

The Arboretum Park Härle is a nonprofit arboretum located on the slopes of the Rhine Valley between Bonn and the Seven Mountains at Büchelstraße 40, Bonn, North Rhine-Westphalia, Germany. It is open twice a month during the warmer months; admission is free.

The arboretum dates back to 1870, when the director of the Rheinische Eisenbahn-Gesellschaft created a large country house in the English half-timbered style, with park plantings that still remain, including two cedars, a Ginkgo biloba, a Sequoiadendron, and an incense cedar. In 1921 the property was acquired by jurist Dr. Carl Härle, who actively planted a wide variety of trees and shrubs. After his death in 1950, his daughters Maria and Regina Härle maintained the property, and ultimately willed it to a nonprofit foundation in 2000.
