"Lost City" Yielding Its Secrets Working with new evidence and a trove of re-examined relics, many of them recovered from the basement of a Yale museum here, archaeologists have revised their thinking about the significance of Machu Picchu, the most famous "lost city" of the Incas. ... [Contrary to previous theories,] Machu Picchu was one of many private estates of the emperor and, in particular, the favored country retreat for the royal family and Inca nobility. It was, archaeologists say, the Inca equivalent of Camp David, albeit on a much grander scale.

This story is an example of teasers run amok. The second paragraph I quoted is the first mention of what the new interpretation of Machu Picchu actually is. It's the eighth paragraph of the story. The other seven paragraphs build the archaeologists' interpretation up to be a new revelation, even though (as the article later admits) it's only a confirmation of a longstanding hypothesis. Either way, I'm glad to see the "royal palace" theory getting some more backing, as that's the explanation that's always struck me as the most plausible.
