What are some things you know that are lost in history?
Wow, I had no idea about that. Have there been any other ancient monuments or structures that have vanished like that?
Yes, there are many examples of lost or destroyed ancient structures. One notable example is the Library of Alexandria, which was one of the largest and most famous libraries of the ancient world. Unfortunately, most of its books and manuscripts were destroyed over time and the exact location of the library is now unknown.
