Last week's Guess Where was a little too easy, so I'm hoping this one is a stumper. Can you guess which ruins these are? Hint: There's a city in America with the same name.

Log in and leave your guesses below. Check back on Monday for the answer.

UPDATE 10/03/11: Nobody got it this time, but this was a hard one. These are the ruins in Memphis, Egypt.
