Machu Picchu, often referred to as the "Lost City of the Incas," is one of the most iconic archaeological sites in the world, located in the Andes Mountains of Peru. While "Pueblo Machu Picchu" might refer to the nearby town of Aguas Calientes, which serves as the gateway to the ancient site, the name "Machu Picchu" itself refers to the historic Inca citadel that was built in the 15th century during the reign of Emperor Pachacuti. The town of Aguas Calientes, often called Pueblo Machu Picchu, is located at the base of the mountain where the ancient site is situated. It serves as the primary hub for tourists visiting Machu Picchu, offering various accommodations, dining options, and services. The town is named after the nearby hot springs ("aguas calientes"), which are a popular attraction for travelers seeking relaxation after exploring the ruins.
