Emperor Trajan, however, created the most complicated and multi-functional Forum Complex of them all. To make space for his giant project, construction workers moved over 61 million cubic meters of dirt! We’ll discuss this and other engineering miracles while ancient Roman administrators, store owners, and people shopping bustle around us. Finally, while ancient Romans said nihil novi sub sole (there’s nothing new under the sun), Trajan’s architect Apollodorus of Damascus proved them wrong! Besides engineering what was then the longest bridge to have been built in Europe (it was just over a kilometer long and spanned the Danube), he also invented a new type of commemorative monument: Trajan’s Column (on which, among battle scene and campaigning, he had his Guinness Book of World Records bridge depicted!). How cool is that?
