The pheasant garden was only opened to the public in 1918. Directly on the Richard-Willstätter-Allee are the Fasanenschlösschen and the teahouse in the Chinese style. The many foreign trees and bushes make up its botanical value. The tree-covered depressions that can be found in the area today were formerly Wildschweinsuhlen and the Biberburgen. They have dried up after Tulla's Rhine correction by lowering the groundwater.
