Cemeteries usually are divided into two broad categories: traditional cemeteries and memorial parks or gardens. A traditional cemetery, the type used for many generations, has upright monuments, usually made of stone. Many traditional cemeteries also have private mausoleums for above-ground interment. Because many have functioned in their communities for over 100 years, traditional cemeteries typically contain a great deal of history, such as architecture, statuary and other art, as well as the personages interred there. They often feature lush landscaping and impressive greenery.
