I've apparently been out of the loop. Yesterday I saw a segment on TV that mentioned the Petronas Towers and decided to check out the world's tallest buildings. First off I was amazed that I hadn't heard of Burj Khalifa, in Dubai. At 2,717 ft it's over 700 feet taller than the second tallest building, the Makkah Clock Royal Tower (1,972 feet) in Makkh. By comparison the Petronas Towers are cute little buildings. It's striking to note that most seem to be located in the Mideast, China and Hong Kong. So, is this another indication of the changing economic/power structure in the world? Should America (and Europe) look to the east with building envy? And can we continue to imagine the Mideast is a backwards culture when they are the ones erecting these incredible buildings? [see below] A list of the world's 200 tallest buildings can be found here: http://www.emporis.com/statistics/worlds-tallest-buildings . Sorry to be so out of touch. I'm sure most of the members here have known about these buildings for a long time.
