The government department in charge of preserving historical buildings, the Oficina de Patrimonio Cultural announced important archaeological findings in the east patio of the Alcazar de Col?n. Fragments of ceramics dating back to the pre-Hispanic days and coins dating back to several periods after the arrival of the Spanish conquistadors have been found. The Alcazar de Col?n, the colonial palace from where the conquest of the Americas was planned, was restored in 1957. At the time, research was not carried out in the environs. Recent research showed that the original level of the patio was 75 centimeters lower than the restored level, which led to the discovery of the colonial time artifacts.
