The Sunnydale Cemetery was the main cemetery in town and seemed to be the cemetery of choice for most burials/funerals. It was also the main slay ground for Buffy Summers who regularly patrolled here, waiting by new graves until the vampire rose and fought her.
It also contained Spike's Crypt and Buffy's gravestone during the time she was dead.
In the Sunnydale cemetery, there is a frequently seen mausoleum with the family name Alpert. One of the show's producers is Marc D. Alpert.
A makeshift cemetery was set up in the parking lot of the show’s studios in Santa Monica, and many cemetery scenes were filmed at the Angelus-Rosedale Cemetery at 1831 W. Washington Boulevard, to the south of Los Angeles' Koreatown.
