According to Plato, the Atlantean Temple of Poseidon’s exterior was coated in silver with gold pinnacles.. The ceiling was ivory variegated with gold, silver and orichalcum [a gold/copper alloy]. At the time of the Incas these metals were abundant in South America. In their capital at Cuzco was the Coricancha, ‘The Place of Gold’, dedicated to Viracocha, that so amazed the Conquistadors in the 1530s. This extrordinary building was once covered with over 700 gold and silver sheets, inside and out. Donnelly calculated that the jewels alone would’ve been worth [in 1880s terms, when his book Atlantis was published] $180 million! The eastern end, the most sacred part, was hung with a huge jewel-encrusted gold plate symbolising the Sun. Below, on golden thrones, sat, enbalmed, Inca rulers. [The kings were the Incas, not the civilization.] Nearby was the Garden of the Sun, a paradise of golden animals, plants and birds. Even the pipes, ornaments and aqueducts were gold. In the centre of a large courtyard flanked by antechambers was a gold-covered octagonal platform. Murray Hope said, in The Ancient Wisdom of Atlantis, that the Great High Temple., in the Atlantean capital, like others in the land, “was octagonal in shape,...surmounted by an equidistant cross”.
There are other similarities between Plato’s citadel and the major buildings of Cuzco. Baths were fed by natural hot and cold springs. [Atlantis and the Cordillera Occidental, where Cuzco is located, were volcanic.] The Inca Atahualpa’s palace had gold and silver basins, and fountains feeding stone channels. Plato said that water from the Atlantean springs was channelled into open and covered cisterns. Both places had life-sized ancestral statues of gold.
In Atahualpa’s apartments, said Garcilaso, “worked in much gold”, were “carved engravings of the figures and exploits of the Inca’s ancestors”. Moreover, the Incas told the Spaniards that the

“first inhabitants of the land [i.e. Peru] were born in pairs just as Plato claimed for Atlantis”.
[J.M. Allen, Atlantis: The Andes Solution, 1998]

Yet confirmation of possible connections between Atlantis and Cuzco comes not just from Plato, but Homer’s Odyssey. Homer tells us that the Temple of Poseidon in the Phaeacian’s land was built of “blocks of quarried stone embedded firmly into the ground”. The surviving lower foundations of the Coricancha, below the Spanish monastery of Santo Domingo, are built from huge ashlar blocks slotted together without mortar. Their solidity, unlike the Baroque edifice on them, has withstood centuries of earthquakes. The Spanish described the palace of Atahualpa in great detail. The Great Hall had gold doors, silver pillars and a ‘brazen’ [bronze] floor. There were gold and silver statues, including dogs guarding the main portals. Homer said not only did the Great Hall of Alcinous’ palace possess such a floor, but that the main entrance had

“golden doors hung on posts of silver...set in the bronze threshold. The lintel...was silver... . On either side stood gold and silver dogs....as immortal sentries.... Golden statues of youths fixed on solid pedestals held flaming torches....to light the....hall by night”.

Both Plato’s Atlantis and Homer’s Phaeacia land are high and rocky. Their respective capitals are ringed and overshadowed by lofty peaks. Plato eulogises about their size, number and beauty, and their rivers and lakes. Homer mentions a “long mountain range”. The Spanish, in 1533, described Cuzco as being “surrounded by high and snowy mountains”. It is located over 11,000 ft up in the Andes. Plato says the plain before the mountains was divided grid-like by canals and bounded by a ditch fed by mountain streams. Speed’s image shows Cuzco was like that. Plato’s Royal City had high triple walls, the outer one bronze-coated, just like the Tartarus of Greek myth The left image depicts three walls around Santo Domingo.
I’m not saying that Atlantis was definitely in Peru, or, that the Royal City was Cuzco. It’s just that the similarities are so striking that it is possible the Incas, like the Aztecs at Tenochtitlan in Mexico, were inspired to ‘recreate’ the ‘homeland’ of their ancient ancestors in their respective capitals.
