Happy Engineer’s Day 2025: Top 8 Engineering Marvels From Around the World
Engineer’s Day is celebrated every year on September 15. It marks the birth anniversary of Sir Mokshagundam Visvesvaraya, one of the country’s most respected engineers. The day is also a tribute to all engineers who help shape the world around us and turn complex ideas into workable solutions.
Channel Tunnel (United Kingdom – France): This tunnel links Britain and France uinder the English Channel. Measuring over 50 kilometres, with nearly 38 kilometres beneath the sea, it is the world’s longest underwater tunnel. (Image: Wikimedia Commons)
Burj Khalifa (United Arab Emirates): It is the tallest skyscraper in the world. Its unique Y-shaped floor plan and reinforced concrete core provide stability against desert winds. The tower hosts homes, offices, and observation decks. (Image: Wikimedia Commons)

Golden Gate Bridge (USA): Once the longest suspension bridge span in the world, this bridge across San Francisco Bay is famous for its engineering to withstand strong winds, earthquakes, and corrosive marine conditions. (Image: Wikimedia Commons)
Millau Viaduct (France): The tallest vehicular bridge in the world, completed in 2004. Its pylons soar above the Tarn Valley. It combines elegant design, structural strength, and minimal environmental disruption. (Image: Wikimedia Commons)
Five Hundred Meter Aperture Spherical Telescope (China): The world’s largest single dish radio telescope, built in a natural karst depression. The engineering involves a deformable reflector, precise control systems, and is crucial for discoveries in astronomy and astrophysics. (Image: Wikimedia Commons)
Great Man-Made River (Libya): It is the largest irrigation network ever constructed, transporting water from ancient aquifers beneath the Sahara Desert. It offers drinking water and irrigation to the arid part of the country. (Image: Wikimedia Commons)
Statue Of Unity (India): Currently the world’s tallest statue (182 meters). Besides its size, its construction involved huge volumes of steel, concrete, and precise engineering due to its height and exposed location. (Image: Wikimedia Commons)
