The Engineering Failure That Almost Destroyed Pisa Forever

The Engineering Failure That Almost Destroyed Pisa Forever The Leaning Tower of Pisa was never just tipping over—by 1990, 14,500 tonnes of hollow marble were on the verge of bursting under catastrophic pressure. Why did 800 years of fixes make it worse, and how did removing soil from the underground finally stop the collapse? #megaengineering #civilengineering #megaprojects #pisa 📌 What You'll Learn In This Video: ✔ Why a 14,500-tonne marble tower was placed on a foundation only three metres deep ✔ How the tower originally leaned North before swinging South into a curved "banana" shape ✔ Why engineers in 1990 realized the structure was about to burst before it ever fell over ✔ The botched "Black September" liquid nitrogen fix that moved the tower in a single night ✔ How removing 38 cubic metres of dirt from the high side stabilized the entire monument ✔ The soil-structure interaction secret that saved Pisa from four massive earthquakes If you enjoy mega engineering projects, megastructures, skyscrapers, architecture, high-speed rail, and construction documentaries, then this channel and video is for you. 👍 Like the video if you enjoyed it. 💬 Share your thoughts in the comments. 📤 Share with your friends 🔔 Subscribe / @megatechbuilds and turn on the notification bell for more amazing engineering and mega project documentaries every week!
