Machu Picchu

Protecting Significant Sites in Egypt, Peru and Beyond

Safeguarding ancient Egyptian cultural treasures in the 1960s laid the groundwork for the UNESCO World Heritage Site program. These designations provide protections for places having outstanding cultural and natural heritage. Both Egypt and Peru have fabulous archaeological sites with World Heritage designations, and I’ve had the good fortune to see many. I hope to visit World Heritage Sites in many other countries.

Buildings That Last

In the earthquake-prone central Andes Mountains, there archaeological sites with monumental adobe and stone block structures standing that were built by ancient people hundreds and even thousands of years ago.

Buildings that promise to last a long time are also being constructed today.

Machu Picchu and Mysterious “Gold” Mortar

Machu Picchu is truly one of the wonders of the world. The spectacular ridge-top site of this city and the fine masonry of royal Inca buildings are stunning aesthetic and technical accomplishments. Early Spanish chroniclers reported "molten gold" was used as mortar during stone block construction, and a research paper by a chemist presents some intriguing insights.

Monuments, Megaliths, and Inca Builders

In the Andes Mountains of South America, the Incas and their ancestors invested enormous amounts of time and labor in the meticulous work of quarrying, transporting, and fitting together multi-ton stone blocks, or megaliths, for monumental construction projects..... The ancient Andean stonework is so impressive that many have found it difficult to believe that mere humans, who lacked draft animals and were using only stone-age tools, could be responsible for the construction.

Water and Power at Chavín de Huántar

Machu Picchu, the city built by the Incas on a steep mountain ridge, is a tremendous engineering achievement – and only one of many impressive constructions by the ancient Andeans. Among these is Chavín de Huántar in northern Peru, with a sprawling temple complex that was once the center of a powerful cult and an important pilgrimage site.
