Top 5: Ancient Observatories - Space Documentary

Ancient cultures attempted to track the motions of the Sun and Moon, measure time, and relate their world to the world above (and below) through glorious and enigmatic structures they built. This document highlights a collection of sites, prehistoric and otherwise, that include artifacts related to tracking the Sun and often the stars. This is not an exhaustive list, just a sampling. Because few written records exist, we can only surmise from the evidence what purpose these sites might have served for their builders. The sites are listed in approximate chronological order.
