Mount Auburn Cemetery
Mount Auburn Cemetery, located in Cambridge and Watertown, Massachusetts, is the first rural or garden cemetery in the United States. It is the burial site of many prominent Boston Brahmins, and is a National Historic Landmark. Dedicated in 1831 and set with classical monuments in a rolling landscaped terrain, it marked a distinct break with Colonial-era burying grounds and church-affiliated graveyards. The appearance of this type of landscape coincides with the rising popularity of the term "cemetery," derived from the Greek for "a sleeping place," instead of graveyard. This language and outlook eclipsed the previous harsh view of death and the afterlife embodied by old graveyards and church burial plots. The cemetery is important both for its historical aspects and for its role as an arboretum. It is Watertown's largest contiguous open space and extends into Cambridge to the east, adjacent to the Cambridge City Cemetery and Sand Banks Cemetery. It was designated a Natio ...
