Chippiannock Cemetery was placed on the National Register of Historic Places on May 6, 1994, for significance in landscape architecture, architecture, and art. Designed by noted landscape engineer Almerin Hotchkiss in 1855, it is an exemplary rural cemetery, part of an early mid-19th-century designed landscape movement that led to the creation of public parks in the United States. The Sexton's House is a significant and rare example of Gothic Revival architecture in Rock Island, and several historic mausolea are significant examples of the Classical Revival style. Chippiannock is also an outdoor museum of over eighty years of historic funerary art, containing numerous significant gravemarkers and monuments that represent the artistic preferences of the mid-late 19th century and the early 20th century, ranging from unpolished simple inscribed tablet markers to Victorian obelisks.
