I want to know the answer to the following question:
Who designed the Parc de l'Orangerie?
All the background I'm provided with is that "The Jardin botanique de l'Université de Strasbourg (botanical garden) was created under the German administration next to the Observatory of Strasbourg, built in 1881, and still owns some greenhouses of those times.". Is that enough to answer the question?
Answer: no
