Machu Picchu

Machu Picchu is an ancient Inca city located high in the Andes Mountains of Peru. Built in the 15th century, it was later abandoned and remained unknown to the outside world for centuries.

The site is known for its precise stonework, terraced slopes, and integration with the surrounding landscape. Buildings were constructed without mortar, yet fit together so tightly that many structures have survived earthquakes.

Today, Machu Picchu is carefully preserved and managed to balance tourism with conservation. It is widely regarded as one of the most important examples of Inca engineering and planning.

Chichén Itzá

Chichén Itzá is located in the Yucatán Peninsula in Mexico. It was built by the Maya civilization and served as a major political, economic, and religious center.

The most famous structure is El Castillo, a large step pyramid designed with astronomical precision. During certain times of the year, shadows on the pyramid create the appearance of a serpent moving down the stairs.

The site reflects advanced knowledge of mathematics, astronomy, and architecture. Today, Chichén Itzá is one of the most visited archaeological sites in the Americas.
