Yes, I think the tower would be similar to a ziggurat.
Some things about Babel I think are interesting - this of course is my own conjecture:
I also recently listened to this podcast - it connects the Tower of Babel and other passages in ways I never thought of before, and ends up explaining a lot about the text of Genesis 11. I definitely recommend their podcast because every one I’ve listened to I’ve learned something new and fascinating about the OT and connecting it to Jesus.
You can google for tower of Babel myths - like flood myths, many cultures have a tower or confusion of language myth. Yes, I do believe it’s history. On a YEC timeline, it also matches the introduction of writing in the ME and lots of languages in that area. Of course, I’m not expecting many here will agree with me.
