The Inca civilization of South America, unlike the Mayan, was still at its height when conquistadors arrived. One of the conquistadors, Cieza de Leon (1518–1560), followed trails from the coast of Peru into the foothills of the Andes and learned from natives about the ruins of a once great city high in the mountains. He presumed that it was an old Inca settlement like those the Spanish found elsewhere in what is now Peru. In 1549, heading inland from Lake Titicaca, which separates Peru from the land-locked nation of Bolivia, de Leon found the remains of the fabled city of Tiahuanaco, which were far greater than he had expected.
The site of the ancient city features large artificial mounds and massive, carved stones, including an enormous entrance called the Gateway of the Sun. Carved from a single block of stone weighing 10 tons, the Gateway features intricate decorations, including a god-figure often identified as Viracocha, who figured prominently in the mythology of the region.
A terraced monument called Akapana, measuring 650 by 600 feet and rising 50 feet high, has a pyramidal shape that levels off to form a high platform. Within that platform are sunken courtyards. Seen throughout Tiahuanaco are skillful examples of masonry and the brilliant use of metals, including copper clamps that hold massive blocks of stones together.
The Gateway of the Sun stands on the northwest corner of a platform temple called Kalasasaya, which is adjacent to a semi-underground temple; the temples form part of an astronomical observatory. Some standing stones placed on the site weigh up to 100 tons. Among other remarkable feats, the residents of Tiahuanaco devised a drainage and sewer system. At 12,500 feet of elevation, Tiahuanaco was the highest city of the ancient world.
As soon as Cieza de Leon reported the remarkable discovery, Tiahuanaco became one of the world's great mysteries, for the local Aymara Indians insisted that the ruins were there long before the great Inca civilization came to the area and conquered it around 1450. Christian missionaries followed Cieza de Leon to the ruins, and these men of learning soon doubted whether the Aymara people could ever have been capable of the craftsmanship and engineering such massive structures required. Legends began to be spread by the missionaries that the structures had been erected in the distant past by giants.
Scientists date the civilization that occupied Tiahuanaco to 300—when a community first began to settle in the area—to 900, when some kind of disruption occurred and Tiahuanaco was abandoned. Those dates match the claim of the Aymara Indians that Tiahuanaco was built and lay in ruins before the Incas came. Other theorists blend scientific finds and local myths, perpetuating the notion that a white race, perhaps Egyptians or Phoenicians, brought civilization to the high plain.
The argument that Tiahuanaco thrived more than 10 thousand years before the dates established by scientific testing was fostered by Arthur Posnansky in his book, Tiahuanaco: The Cradle of American Man (1945). Noting that the platform temple Kalasasaya was used as an astronomical observatory, Posnansky determined that it pointed precisely to solstice alignments in 15,000 b.c.e. Taking into account the very gradual shifting of Earth's axis, Posnansky postulated that arid plain was once below water, part of Lake Titicaca, and that Tiahuanaco was once a major port city. The ancient citizens of Tiahuanaco were members of a superior culture who had introduced a golden age to the area. The founders of Tiahuanaco were taller and had distinctive facial characteristics quite apart from the high-cheekboned visages of today's dwellers of the high plateau.
In Posnanksy's view, the most startling tale told by the few artifacts left in the city was of a New World civilization that was amazingly similar to that of ancient Egypt. The Calassassayax (house of worship), he believed, was so similar to the Egyptian temple of Karnak in design and layout that its relative dimensions made it almost a scale model of the Old World structure. The stones used in the temple at Tiahuanaco are fitted and joined with their joints and facing parts polished to make a nearly perfect match. The Incas did not build in such a manner, but the ancient Egyptians did.
And then there were the buildings constructed of massive, polished stones, many tons in weight, that had been placed in such a manner that only a people with advanced engineering methods could have designed and transported them. If this were not enough of an impossible situation, the particular andesite used in much of the Tiahuanacan construction can only be found in a quarry that lies 50 miles away in the mountains.
The surgeons of Tiahuanaco were skilled in trepanning the brain, as were the Egyptian physicians. Posnansky uncovered skulls with well-healed bone grafts, which offered silent testimony to the skill of the ancient doctors and their knowledge of anatomy. Some archaeologists receptive to Posnansky's theories argue that the credibility of cultural coincidence is stretched considerably when related to brain operations. It is possible to accept the fact that two widely separated cultures, such as the Egyptians and the unknown people of Tiahuanaco, may have developed a form of brain operation, but that both cultures used identical instruments and methods, seems unusual to say the least. The instruments are of high-grade copper and include drills and chisels. In themselves they indicate an advanced degree of metallurgy, knowledge of simple machinery, and development of surgical practices far more detailed than can be expected in primitive societies.
Posnansky's theories won a popular readership, but were not widely accepted among scientists. At sunrise on dates of the equinox, for example, the Sun appears on the staircase of Kakassasaya. There is no need to believe that it was built at a precise time to point to a precise astronomical alignment. The port city idea was also quickly disputed. Areas that would have been submerged included neighborhoods of dwellings that share similar dates with the larger structures, and the surrounding countryside where farms were located also would have been underwater.
Radiocarbon dating suggests instead that Tiahuanaco was founded around 400, and after three centuries of gradual settlement, the city was abandoned around 1000. In the interim, the settlement had grown from a ceremonial center to a major city inhabited by 40,000 to 80,000 people.
Regular archaeological excavations have been underway in Tiahuanaco since 1877. The semi-subterranean temple next to the Akapana yielded a 24-foot tall monolith in 1932. That find and the generally arid climate helped sustain the idea that Tiahuanaco served primarily as a ceremonial center. Later finds, however, showed that it had been a thriving city, and dates for the time settlement and abandonment were established. Why the place was abandoned, however, remains a mystery to conventional archaeologists.
However, according to Posnansky, it was the climactic changes at the end of the Ice Age that contributed to flooding and the destruction of Tiahuanaco, wiping out its inhabitants and leaving the great structures in ruins. Posnansky died in 1946, convinced that he had traced the influence of Tiahuanaco on the native culture as far north as the coastal deserts of Peru and as far south as Argentina.
Most other archaeologists take much more conservative views. As with the Mayans, they argue, the ancient Indians of Tiahuanaco might have had too much of a good thing. There is evidence that they were victims of a natural catastrophe, but it was a prolonged drought, rather than Posnansky's great flood, that probably overwhelmed them. Drought conditions set in for an extended period, and the Aymara could no longer support a massive population and large-scale construction projects. People began abandoning the city around 1000. The Incas conquered communities remaining in the area around 1450. Then the Spanish came to Tiahuanaco about one hundred years after the Incas had moved in.
Still the questions remain: just who were the natives that thrived at Tiahuanaco and how did they construct such elaborate structures?
The Aymara, meanwhile, still live in the region. They outlasted the early Spanish settlers around Tiahuanaco, who never quite mastered the area's harsh conditions. The plain became a desert again after the Spanish farmed it, for they never learned to use a technique of the ancient dwellers of Tiahuanaco. The mysterious unknown people farmed on raised fields, which were filled and built up with soil from surrounding areas. Canals between the fields kept them watered, and by farming on raised fields the crops were kept safe from the danger of frost and erosion by water.

Tiahuanaco (tyäwänä´kō), ancient native ruin, W Bolivia, 34 mi (55 km) S of Lake Titicaca on the Tiahuanaco R. in the S central Andes, near the Peruvian border; also called Tiwanaku or Tiahuanacu. Nearly 13,000 ft (3,962 m) above sea level, Tiahuanaco was probably the center of a pre-Inca empire and is believed by some to have been built by the Aymara and to have had some 30,000–40,000 inhabitants. Much of the construction is unfinished. Building was begun at some time before AD 500, and there is evidence of additional construction c.1100–1300. About 1000, Tiahuanaco culture spread to E Bolivia, N Chile, and Peru; the culture flourished for about 200 years. Built of massive blocks weighing up to 100 tons and brought from several miles away, the structures of Tiahuanaco consisted of terraced pyramids, courts, temples (some containing monolithic stone statues of human figures), and urban areas covering some 2.3 sq mi (13.6 sq m) and are superb examples of masonry. The stones, fitted together without mortar, were cut, squared, dressed, and notched with a precision equaled in no other aboriginal South American civilization, not even the Inca. Construction is largely of the platform or monolithic type decorated by conventional incised carving or heads in low relief. The creators of Tiahuanaco excelled as well at ceramics; Tiahuanaco painted pottery is one of the great achievements of pre-Columbian art. Also found at Tiahuanaco were goods made of copper, silver, and obsidian, thought to have been used by the society's elite members.
