From Casinos in Las Vegas to museum facades, modern architects and engineers take inspiration from ancient structures such as the Great Pyramids and Parthenon. Now an infographic details some of the techniques used to build these inspirational and lasting monuments. It includes the eco-friendly Roman concrete and the Incas' ability to cut stone and slot pieces together like a jigsaw to build Machu Picchu. It also shares the latest thinking on how experts argue mysterious structures were made. Experts still debate about some feats of engineering, such as how vast stones were lifted into place to build the iconic pyramids at Giza.Infographic details techniques used to build inspirational monumentsIncludes Roman concrete, Greek geometry and Turkish cutting precisionSome mysteries are unsolved, including how stone was moved to build the pyramids and how the Incas created such sharp joins at Machu Picchu
But perhaps the reason why the testament to _ engineering has lasted so long is a secret concrete recipe, which experts are still trying to emulate today.
