Architecture art that you can interact with; you can walk up to it, touch it and even venture inside it. It's impossible to even imagine doing anything similar with any other type of art.
What's even better is that these days you don't even have to be in the big cities to see the most amazing and spectacular feats of architecture. More and more frequently designers and builders are heading out further and wider, to take awe-inspiring buildings to every corner of the globe. Prepare to be blown away, as some of the buildings seem to defy the laws of both convention and physics.
