Located in the Casma Valley on Peru's north-central coast, this archaeological complex represents one of the oldest astronomical observation systems in the Americas. The site consists of a series of thirteen towers arranged in a linear pattern on a hilltop, constructed during the Early Horizon period. These towers were systematically positioned to mark the rising and setting points of the sun throughout the year, demonstrating sophisticated knowledge of astronomical cycles among pre-Columbian coastal societies. The ensemble reflects the cultural and scientific achievements of early Andean civilizations and their ability to integrate astronomical observation into their settlement patterns and ritual practices. The towers, built from stone and adobe, remain visually distinctive features of the landscape and provide material evidence of ancient practices that influenced subsequent Andean cultures. This archaeological complex is significant for understanding the development of astronomy and calendrical systems in ancient Peru.
