Established in the 1870s, Calvary Cemetery became the final resting place for over 1,800 individuals, although local rumors suggest as many as 4,000 bodies may lie interred within its grounds. Among those buried were members of notable San Diego families, including the Bandini family, former owners of the Cosmopolitan Hotel in Old Town, and the Couts family, who once possessed Rancho Guajome Adobe. Father Antonio Ubach, a significant figure in San Diego’s history, having served as the parish priest for four decades during the 19th century, was also laid to rest here. The Couts family’s contributions extended to mapping the US-Mexico boundary after the Mexican-American War and even naming streets in what is now Old Town San Diego. Colonel Cave Johnson Couts died in 1874, with his wife joining him in burial 24 years later.

Despite the historical significance and the presence of these prominent families, Calvary Cemetery faced neglect over time. In a controversial decision in the 1970s, the headstones were removed and discarded into a ditch, and the cemetery was transformed into Pioneer Park. This act effectively erased the visible history of the site, turning a place of remembrance into a public park. It wasn’t until the early 1980s, during trolley construction, that a headstone was rediscovered in a ditch, bringing the cemetery’s forgotten past back into public consciousness. In response to the ensuing outcry, the city hired a historian to assess the remaining headstones. Select stones deemed historically important were then retrieved and arranged in a memorial row within the park, serving as a somber reminder of the thousands of individuals still buried beneath.

The juxtaposition of a cheerful park and a former cemetery creates an undeniably eerie atmosphere. One local resident recounted playing in the ravine as a child, unknowingly climbing on discarded tombstones, mistaking them for concrete blocks. The thought of children playing above unmarked graves is unsettling, and Pioneer Park has gained a reputation as a hotspot for ghost hunters. Many claim to sense a palpable, unhappy energy in the park, particularly after dark, although caution is advised when visiting at night due to safety concerns in the area.
