How can Merlin have attended Hogwarts and be placed in the Slytherin House, if Hogwarts is built in 900s
It also doesn't really make much sense if Hogwarts is built way earlier, because as far as I'm aware stone castles are not a thing in Britain until the Norman Conquest. Unless you think the founders knew some advanced mason technology and kept the muggles completely away with magic or something.
I am not even going to delve into the school's modern plumbing system built in with the Chamber of Secrets.
