After the Heppenheim moat was filled in after 1849, a park-like area developed in front of the southern city wall and the former official winery. Monuments reminiscent of military conflicts and their consequences were erected here. In the section of the moat to the west of the city wall, a garden separated by an enclosing wall was created with the expansion of the district office from 1904/07. After the district of Bergstraße had allowed the city of Heppenheim to use it, the walls were dismantled and the "district office garden" was renamed "Marianne-Cope-Garten" in 2017 in memory of St. Sister Maria Anna Koob, who was born in Heppenheim in 1838. Marianne Cope, who emigrated to America, joined the Third Order of Franciscan Sisters at the age of 24, was appointed Superior in 1875 and two years later elected Superior General. She devoted 30 years of her life to caring for lepers on a nearly inaccessible peninsula of Moloka'i. She not only took care of the physical suffering of the lepers, but also wanted to give the forgotten their dignity back.
 
The memorial complex and the Marianne Cope Garden form a common park with monuments from different historical eras. Also on display is a pavement found in Heppenheim in 1955 from a Roman road running along the Bergstrasse.
