Forgotten for centuries, the site was brought to worldwide attention

Machu Picchu was built around the year 1450, but abandoned a hundred years later, at the time of the Spanish conquest of the Inca Empire. Forgotten for centuries, the site was brought to worldwide attention in 1911 by Hiram Bingham, an American historian.

In the above writing copied from a website, is the second sentence grammatically correct as is? (Sorry, I don't know how to provide the link.)

Also, how about these alternatives? Are they all fine?

(1) Having been forgotten for centuries, the site was brought to worldwide attention in 1911...

Or

(2) After having been forgotten for centuries, the site was brought to worldwide attention in 1911...


Or

(3) After being forgotten for centuries, the site was brought to worldwide attention in 1911...
