The odd band-like structure at the top of the Pyramid of the Sun in Teotihuacan, Mexico, is the result of its construction techniques and the use of materials available at the time. This unique feature is believed to reflect the architectural styles and spiritual beliefs of the Teotihuacan civilization. The band-like design may symbolize various cultural aspects, possibly including astronomical alignments or religious significances, corresponding to the sun's position.

Additionally, the varying stonework and layering techniques seen in the band's construction indicate a sophisticated understanding of architecture and engineering among the ancient builders. This not only illustrates their skill but also highlights the importance of the Pyramid of the Sun as a monumental structure within the context of Mesoamerican civilization, pointing to a blend of practicality and symbolic representation in their architecture.
