What is the world's tallest building? How much taller is it than the world's tallest structures 100 or 200 years ago? Focusing on three distinctive moments in history, the infographic shows a striking development in height, location, purpose and materials: from the sandstone cathedral "Straßburger Münster", highest building in 1824, to the iron "Eiffel Tower", highest structure in 1924, to the almost 830 meters tall Dubai skyscraper "Burj Khalifa" with its glass facade (the "Washington Monument" and the "Empire State Building" being the in-between markers).
