Well I've seen plenty of landmarks but I'm not too sure how many I really dreamed about seeing in advance.

Big Ben - a couple of times. I've got relatives in London.
Empire State Building - was pretty cool. I like that sort of 1920's art deco design. The view was okay but a bit misty.
Ground Zero - they do a pretty good job of blocking any clear view of the place.
Statue of Liberty - not as big as you'd think.
Ellis Island - dull to someone who isn't descended from American immigrants but they do sell damn good coffee.
Niagara Falls - also not as big as I thought but still pretty damn huge. And wet.
Golden Gate Bridge - windy. Very, very windy.
Alcatraz - also quite small but kinda creepy.
Plenty of landmarks in Israel like Masada and the Western Wall. I also visited the Church of the Holy Sepulchre, which is where Jesus was crucified and buried.

What do I want to see?
Rome, to see the Coliseum and also all the more modern sculptures and artwork (ie the ones constructed in the last 400 years).
Spain to see the architecture of Antonio Gaudi.

There's probably some more but I've gone blank.
