Archaeoastronomical Sites: Mapping Ancient Skies
Archaeoastronomy is the study of how ancient societies used astronomy and celestial events in their cultures. Scientists in this field examine ancient buildings, artifacts, and writings to understand how people in the past observed the stars and planets. By looking at things like how monuments were aligned with the sun or stars, decoding symbols related to astronomy in art and architecture, and studying ancient calendars and beliefs about the cosmos, archaeoastronomers piece together how ancient civilizations viewed and interacted with the sky. Civilizations around the globe have looked to the heavens for guidance and inspiration. Through careful analysis and research, archaeoastronomy helps us learn more about how astronomy influenced the development of human societies and their beliefs.
Across the globe, archaeoastronomical sites reveal how ancient civilizations observed and understood the skies. These locations provide insight into celestial cycles, agricultural planning, ritual practices, and even long-term communication through precise alignments. From Asia to the Americas, these sites demonstrate extraordinary knowledge of astronomy and landscape design.

Conclusion
These archaeoastronomical sites demonstrate that ancient peoples were not only observers of the heavens but also skilled engineers and planners. Their alignments, often to the sun, moon, and stars, reveal a deep understanding of celestial mechanics and an enduring desire to connect human life with the cosmos. Each site — from the deserts of Peru to the hills of Ireland — is a testament to the intelligence, ritual, and creativity of our ancestors.
