Located in Old Town, second oldest cemetery in San Diego had burials from 1849 to 1880. In 1933, the San Diego Historical Society restored in the cemetery based on descriptions and photographs, but over the years some of the boundaries have been moved to accommodate for city development. In 1889 a horse-drawn streetcar line was built through part of the cemetery, which later became San Diego Avenue. In 1942 it was paved over, leaving as many as 18 graves under the street and sidewalk. The Ghosts and Gravestones San Diego Tour takes visitors on an intimate nighttime journey through the cemetery to explain the haunted history of this Old Town landmark.
