With the Spanish conquest in the 16th century, the urban structure of the Inca imperial city of Cuzco was preserved and temples, monasteries and manor houses were built over the Inca city. IntegrityThe City of Cuzco maintains the spatial organization and most buildings from the ancient Inca Empire capital and the Viceroyalty. The factors threatening the attributes of the City of Cuzco have not affected the authenticity of its basic elements. However, the City of Cuzco has developed the cadastre and has updated inventory and the declaration of monuments. A management plan for the City of Cuzco, which is fundamental for protection, was developed in 2005 and is currently being implemented.
