The partners decided to buy land in the ridge of El Llano (today Bolivar Street). They agreed to the founding of a new cemetery, seeing the lack of one worth their families, since the Cemetery of San Lorenzo, which was founded in January 1828, was the only one there and, therefore, was too small to continue providing the service to the families of Medellín. Specifically, the cemetery was founded on July 8, 1842, under the initiative of Pedro Uribe Restrepo, who called a meeting of important families of the Villa de la Candelaria.
This time was characterized by great advances in the town, such as a population increase and strengthening of major economic groups, wars fought between political parties, colonization of western Colombia, the consolidation of trade, the birth of the industry, railroad building and navigating the Magdalena River. The Cemetery San Pedro was founded in 1842, when the small town of La Candelaria (present-day Medellín) had 9000 inhabitants and only 16 years had passed since it became the new capital of Antioquia.
