A line of thirteen rectangular towers, built along a north-south hilltop ridge within a ceremonial complex in coastal Peru dating to c. 300 BC, appears to represent the oldest known solar observation device in the Americas. The fact that this device functions throughout the seasonal year, and still functions today, makes it unique on the planet. The broader archaeological evidence suggests that observations of sunrise and sunset against the thirteen towers served to regulate a social and ritual calendar while reinforcing a solar cult that helped to lend legitimacy and authority to a rising warrior elite. Recent archaeoastronomical work has identified a wider range of potentially significant alignments, possibly including some lunar ones, visible from publicly accessible places rather than just by a few high-status individuals. The site and its interpretation also illustrate some fundamental issues of archaeoastronomical methodology and practice that are of broader significance.
