The Panteón Civil de Dolores is the largest cemetery in Mexico and contains the "Rotonda de las Personas Ilustres" (Rotunda of Illustrious Persons). It is located on Constituyentes Avenue in Miguel Hidalgo borough of Mexico City, between sections two and three of Chapultepec Park. The history of the cemetery goes back to 1870 when Juan Manuel Benfield, owner of El Rancho de Coscoacoaco (his wife was Concepción Gayosso y Mugarrieta sister of Eusebio Gayosso) set aside an area of his ranch measuring 240 square hectometres (590 acres), called La Tabla de Delores, on which to found a cemetery. In 1875, the cemetery was opened and named El Panteon Civil de Dolores. Juan Manuel Benfield founded the Cemetery in honor of his sister who died in Veracruz shortly after she had arrived from London with their parents. As they were Anglicans, and all cemeteries in Veracruz were consecrated for use only by Roman Catholics, the only suitable burial ground to be had was on the beach.
