The current issue of Astronomy has an interesting article about the Temple of the Fox, which is being excavated in Peru. It is approximately 4200 years old and is the oldest observatory to have been found in the Western Hemisphere. It is aligned with the solstices, and also with the rising of a dark-cloud astronomical figure known as the Fox. I am very curious to know more about the civilization that built it. Does it even have a name? Apparently, it predates even the Olmecs, and was probably contemporaneous with whatever civilization built Stonehenge.
