The Colon Cemetery began in 1876 by the Spanish architect Calixto Arellano de Loira y Cardosa, who was also the first burial (he died before the cemetery was completed). The cemetery has over 500 mausoleums, chapels and family vaults, and covers 140 acres. There are over 800,000 graves at the Colon Cemetery. After three years remains are removed from tombs and placed in an ossuary building. This is a practice common in Spain, and brought over to Cuba by the Spanish settlers.
