In 1855, Adolph Strauch, a renowned landscape architect, was hired to beautify the grounds. His sense and layout of the "garden cemetery" made of lakes, trees and shrubs, is what visitors today still see. He created a more open landscape by setting limits on private enclosures and monument heights. The results of the redesign earned Strauch praise in the U.S. and abroad, including from Frederick Law Olmsted and the French landscape architect Edouard André. On March 29, 2007, the cemetery was designated a National Historic Landmark. The Spring Grove Cemetery Chapel is listed separately on the National Register of Historic Places.
