  Machu Picchu, one of the seven wonders of the world, was built by the Incans in the 15th century, sometimes referred to the "Lost City of the Incans". It is theorized that it was used as a retreat by the Incan elite. Machu Picchu was surrounded by terraces for agricultural use. After the Spanish conquest, the site was lost until the 20th century.
  
  Other famous architectural sites in Peru include the fort of Sacsayhuaman, famous for its high stone walls, and the city of Chan-Chan, the capital of a civilization called the Chimu culture, located on what is now the site of Trujillo. It was the largest city in Pre-Colombian South America. It is believed to have been built in the mid-800s, and held 40-60 thousand people. It is the largest adobe city in the Americas, and believed to be the second-largest in the world.
  
  Other famous examples of Peruvian colonial architecture include the Cathedral of Lima, the Basilica of San Francisco in Lima, the Cusco Cathedral, and the Church of San Agustin.
