If you love architecture, visit Dubai! It seems everything they build has to be the biggest and craziest in the world. To name a few (and I do mean a few) they have the largest mall in the world (sorry Edmonton), are building the tallest tower (sorry Toronto) and are building entire cities on several man made islands which also beat the record (sorry Hong Kong). You should see the place. The city is basically one gigantic consturction site!

Oh and this picture is of a ceiling in one of the malls which resembles a sailing boat.
