Burj Dubai

Emaar's Burj Dubai recently became the tallest structure anywhere in Europe and the Middle East. But from a medium-to-close vantage point it doesn't actually seem that tall. It's only when you can see it from a distance (in this case Nadd Al Sheba) that the effects of perspective and foreshortening disappear, and you can really see how it towers (bad pun, sorry) over the other buildings on Sheikh Zayed Road.
