Please accept "Houses of the Parliament" and "Elizabeth Tower" for the first picture because they are actually seen on the photo while Big Ben is not seen since it's inside the tower. Also for the Acropolis you should choose a different photo to avoid confusion because the Acropolis is not just the Parthenon but the whole hilltop with multiple buildings.
Thanks for your comment
Also why is the Parthenon there twice?
It is not Parthenon twice, one of them is something else
I’m still working on it, but thanks for your comment.
Thank you
