From water systems to roads and bridges, ancient civilisations were solving infrastructure challenges thousands of years ago, often with nothing more than basic tools, clever design and a deep understanding of their environment. What's even more impressive? Some of these assets are still in use today. Here are our top 10 ancient engineering projects that have well and truly stood the test of time. 1. The Cornalvo Dam, Spain Built in the 1st–2nd century CE, this Roman dam st

You’ve likely driven past dams, admired flowing rivers or noticed hydro plants on project lists, but how did we get from simple waterwheels to massive renewable power stations? The story of hydroelectricity is one of innovation, adaptation and, ultimately, a major steppingstone in the world’s energy mix. From Waterwheels to Watts Long before electricity was a thing, humans used water for power. Waterwheels turned grain, pumped water and drove early industry. But it wasn’t unt

On 24 October 2001, a fire broke out inside the Gotthard Road Tunnel in Switzerland. By the time it was over, 11 people had lost their lives, the tunnel was closed for two months, and Europe’s approach to tunnel safety had fundamentally changed. What happened The Gotthard Road Tunnel runs for 16.9 kilometres beneath the Swiss Alps, carrying two-way traffic in a single tube. On the morning of the fire, a heavy goods vehicle drifted across the centre line and collided with an
