The Egyptian Pyramids have been drawing crowds for millennia. Unfazed by earthquakes, erosion or vandalism, they’ve endured the collapse of the civilisation that built them and the transformation of the Sahara from lush grassland into today’s vast desert.

Of these, the Great Pyramid of Giza – completed in 2540 BC – is unrivalled, with superior materials, engineering and design to any built before or since. Ancient Greek tourists would travel thousands of miles to gawk at its towering limestone steps, which were so highly polished they were said to glow; their names can be found carved into its walls to this day.

Remarkably, Cleopatra lived closer in history to today’s tallest building – the Burj Khalifa – than she did to this monumental tomb. When the last mammoths died out, it was already 1,000 years old….do today’s skyscrapers stand a chance of outlasting them?

It’s a question I’ve thought about often – what are we creating today that will last a thousand years?
