Mount Calvary Cemetery is a Roman Catholic cemetery in Columbus, Ohio, located west of downtown next to Cooper Stadium and Green Lawn Cemetery. It is the oldest active Catholic cemetery in Franklin County. It is maintained by the Roman Catholic Diocese of Columbus, and has approximately 40,000 interments over 40 acres.
Mount Calvary is divided into two sections that were historically paid for and separately maintained by two parishes of different ethnic backgrounds. The north section, "Holycross," was for the German parish, and the south section, "Cathedral", was for the Irish parish. Separating the two sections is the "Priests' Circle," reserved for clergy.
The cemetery was established in part to replace the old St. Patrick's Cemetery, which was located in downtown Columbus and had become encircled by the city's growth. A plot of just over 25 acres of land, outside the city's original limits, was purchased in 1865 by John F. Zimmer in trust for the Diocese of Columbus, and burials on the site also began that year. Zimmer purchased an adjoining two-acre plot in 1866, and sold the two plots to the Diocese in 1868. The land was further expanded in 1871 by three plots purchased by Father John Ambrose Watterson, later Bishop of Columbus.
