Machu Picchu: The Lost City of the Incas

On July 24, 1911, Yale historian Hiram Bingham III — guided by a local farmer — reached a cloud-shrouded citadel at 2,350 meters in the Andes. What he found was Machu Picchu: over 150 buildings connected by 3,000 stone steps, built by the Inca Empire in the 15th century and abandoned during the Spanish conquest. Though Peruvian explorers had reached the site as early as 1901, Bingham's expedition and National Geographic's 1913 publication of 244 photographs brought global fame.

Designated a UNESCO World Heritage Site in 1983 and named one of the New Seven Wonders of the World in 2007, Machu Picchu sits 85 km from Cusco (area code 84). It's part of the Qhapaq Ñan, the Inca road network spanning 30,000+ kilometers across six countries — itself a UNESCO site since 2014.

Lima: Food Capital of the Americas

Lima has produced two World's Best Restaurant winners: Central (chef Virgilio Martínez, #1 in 2023) and Maido (chef Mitsuharu Tsumura, #1 in 2025). Central's menu is organized by Peruvian ecosystems categorized by altitude. Maido pioneered Nikkei cuisine — the fusion of Japanese and Peruvian culinary traditions born from over a century of Japanese immigration to Peru.

Peru's culinary heritage includes Chifa (Chinese-Peruvian fusion, from the ~2 million Chinese laborers who came in the 19th century), ceviche (raw fish cured in citrus, the national dish), and an extraordinary diversity of ingredients. Peru is the birthplace of the potato — approximately 3,000 native varieties grow in the Andes, where potatoes were first domesticated 7,000-10,000 years ago near Lake Titicaca. The International Potato Center (CIP) is headquartered in Lima.

Peru's Extraordinary Biodiversity

Over 60% of Peru's territory is Amazon rainforest, making it one of the world's 17 megadiverse countries. Peru hosts the largest number of bird species in the world, the third-largest number of mammals, 8% of global amphibian species, and 10% of the world's plant species. The country stretches from Pacific coast desert through the Andes mountains to dense Amazon jungle — three entirely different ecosystems in a single nation.

Lake Titicaca, at 3,812 meters (12,507 feet), is the world's highest commercially navigable lake and one of fewer than 20 ancient lakes on Earth at approximately 3 million years old. The Nazca Lines — over 1,300 km of geoglyphs etched into the desert floor between 500 BC and 500 AD — remain one of archaeology's great mysteries and have been a UNESCO World Heritage Site since 1994.
