Interesting, this is about a 45 minute drive away from me and I've never heard about it until now.
I can't find the exact location though, I wonder if it's open to the public to visit?
If you're in the area don't miss the Mỹ Sơn ruins ("perhaps the longest inhabited archaeological site in Mainland Southeast Asia") or the old French EFEO museum, now the Museum of Cham Sculpture in Da Nang. https://en.wikipedia.org/wiki/M%E1%BB%B9_S%C6%A1n

Austronesian language family is wild. How could a language family be spoken both in New Zealand and Madagascar blows my mind. At least indo-european is connected by land, but an entire language family that spans thousands of kilometers across sea sounds something straight up from a Tolkien book.
