The History of the Archaeological Site of Sacsayhuamán
What Does Sacsayhuamán Mean?
The name Sacsayhuamán comes from Quechua and means “satisfied hawk.” In Andean cosmology, the hawk was a sacred bird and a symbol of protection. It is believed that the site was given this name due to its strategic location and defensive role in Cusco, the capital of the Inca Empire.
What Role Did Sacsayhuamán Play During the Inca Civilization?
Sacsayhuamán was a military fortress, a ceremonial center, and an astronomical observatory. Its high position over Cusco allowed it to defend the city and host religious ceremonies, such as Inti Raymi, the festival of the sun. Additionally, it was a place of learning and gathering for Inca nobility.
The Architecture of Sacsayhuamán
Architectural Features
The architecture of Sacsayhuamán is impressive due to its complexity and the precision with which the stones were assembled. This monumental construction reflects the Incas’ mastery of engineering and their deep understanding of the region’s geography.

Enormous Stone Blocks
The walls of Sacsayhuamán are composed of giant stone blocks, some weighing over 120 tons. These stones were carved and fitted together without mortar, which has preserved the structure for centuries.
Assembly Technique
The Incas used the “sillar” technique, which involved precisely carving the stones to fit perfectly. This method provided great stability and allowed the walls to withstand earthquakes due to their seismic-resistant design.
Zigzag Shape
One of Sacsayhuamán’s most distinctive features is the zigzag shape of its walls. This design strengthened the structure, making enemy attacks more difficult, and symbolized the serpent, a sacred animal in Andean culture.
Terraces and Platforms
The complex has terraces and platforms used for defense and religious ceremonies. From these terraces, there is a panoramic view of Cusco and the Sacred Valley, allowing the Incas to monitor access to the capital.
Underground Foundations
Sacsayhuamán’s underground foundations provide structural stability, preventing collapses and helping the site withstand the frequent seismic activity in the region.
Use of Courtyards and Plazas
At Sacsayhuamán, courtyards and plazas served ceremonial, military, and social functions. These spaces were key for festivals and gatherings of the Inca elite.
The Main Plaza is the largest area of the complex and is believed to have been the site of religious ceremonies and political events. Today, it is the stage for Inti Raymi, the most important festival honoring the Sun God.
Additionally, these courtyards were used for military training, as Sacsayhuamán played a strategic role in Cusco’s defense.
Height and Weight of the Stones
The fortress is located at 3,700 meters above sea level, and some of its stones reach heights of up to 9 meters and weigh 120 tons. The height and weight of the stones are evidence of the Incas’ teamwork and organization, as they used advanced techniques to transport and assemble them without modern tools.
