1. The Millau Viaduct (France)
When discussing modern engineering, the Millau Viaduct often gets overshadowed by flashier projects, yet it remains a masterpiece of design and ingenuity. Spanning the Tarn Valley in southern France, this cable-stayed bridge is the tallest in the world, with its highest point reaching 343 meters (higher than the Eiffel Tower).
Why It’s Remarkable:
Designed by Sir Norman Foster, the bridge combines elegance and functionality.
It was built to address traffic congestion between Paris and the Mediterranean.
Engineers used a unique “push-launch” method to assemble sections of the bridge.
Despite its significance, the Millau Viaduct is rarely highlighted among the great modern engineering works.

2. The Thames Barrier (United Kingdom)
Completed in 1984, the Thames Barrier protects London from tidal surges and flooding, a growing concern due to rising sea levels.
Why It’s Remarkable:
It consists of 10 movable gates that can rise to block tidal waters.
The barrier protects over 1.25 million people and vital infrastructure.
Its innovative design allows it to withstand the test of time and evolving climate challenges.
This engineering marvel quietly ensures the safety of Londoners, yet it seldom receives the recognition it deserves.
3. The Falkirk Wheel (Scotland)
The Falkirk Wheel, completed in 2002, is a rotating boat lift that connects two canals with a 24-meter height difference.
Why It’s Remarkable:
It’s the only rotating boat lift in the world.
The design is both functional and visually stunning, symbolizing Scotland’s engineering prowess.
It consumes minimal energy, requiring just 1.5 kWh (equivalent to boiling eight kettles) per rotation.
Despite its uniqueness, the Falkirk Wheel is often overlooked compared to other global landmarks.
4. The Itaipu Dam (Brazil-Paraguay Border)
Once the world’s largest hydroelectric dam, Itaipu, completed in 1984, provides 90% of Paraguay’s electricity and 15% of Brazil’s power.
Why It’s Remarkable:
Spanning 7,919 meters across the Paraná River, it’s a colossal structure.
The dam produces 14,000 MW of power annually, making it a renewable energy giant.
Its construction displaced a massive waterfall, the Guaíra Falls, which was submerged in the dam’s reservoir.
Itaipu’s monumental impact on energy generation is undeniable, yet it rarely features in discussions about sustainable engineering.
5. The Palm Jumeirah (United Arab Emirates)
Dubai’s Palm Jumeirah, an artificial archipelago shaped like a palm tree, is an engineering wonder that transformed urban design.
Why It’s Remarkable:
Built using 94 million cubic meters of sand and 7 million tons of rock.
Engineers used GPS and satellite imaging to achieve its precise shape.
It redefined luxury real estate and boosted Dubai’s tourism industry.
While it garners some attention, the Palm Jumeirah is often overshadowed by newer projects in Dubai.
6. The Akashi Kaikyo Bridge (Japan)
Completed in 1998, the Akashi Kaikyo Bridge connects Kobe and Awaji Island, making it the world’s longest suspension bridge.
Why It’s Remarkable:
The main span stretches 1,991 meters, an engineering marvel in bridge design.
It was designed to withstand earthquakes, typhoons, and strong tidal currents.
During its construction, the Great Hanshin Earthquake struck, shifting the bridge towers by a full meter—a challenge engineers overcame seamlessly.
Despite its record-breaking design, the Akashi Kaikyo Bridge is seldom recognized in discussions about global engineering feats.
7. The Seikan Tunnel (Japan)
Running 240 meters below sea level, the Seikan Tunnel connects Honshu and Hokkaido and is the world’s longest undersea tunnel.
Why It’s Remarkable:
Spanning 53.85 kilometers, it was built to withstand frequent earthquakes in the region.
It combines railway transportation and disaster resilience, ensuring safe transit across Japan’s islands.
The project took 24 years to complete, involving immense labor and advanced tunneling techniques.
The Seikan Tunnel’s significance is often eclipsed by projects like the Channel Tunnel in Europe.
8. The Great Man-Made River (Libya)
In the arid landscapes of Libya, the Great Man-Made River supplies water to millions, making it a lifeline for the country.
Why It’s Remarkable:
It’s the largest irrigation project in the world, consisting of 2,820 kilometers of pipelines.
The system taps into ancient fossil aquifers deep beneath the Sahara Desert.
It delivers over 6.5 million cubic meters of water daily to cities and agricultural areas.
Despite its monumental scale, this project remains largely unknown outside of specialized engineering circles.
9. The Oresund Bridge (Denmark-Sweden)
The Oresund Bridge, completed in 2000, is an engineering marvel that combines a bridge and an undersea tunnel to connect Denmark and Sweden.
Why It’s Remarkable:
It spans 8 kilometers as a bridge before transitioning into a 4-kilometer tunnel.
The design minimizes environmental impact and maintains uninterrupted shipping traffic.
It symbolizes European connectivity, fostering cross-border economic and cultural ties.
Though vital for Scandinavia, the Oresund Bridge often gets overlooked in favor of larger, more visually striking structures.
10. The Panama Canal Expansion (Panama)
The Panama Canal, an engineering marvel in its own right, underwent a historic expansion in 2016 to accommodate larger ships.
Why It’s Remarkable:
The expansion included constructing a new set of locks, doubling the canal’s capacity.
Engineers used 4.4 million cubic meters of concrete, creating gates 33 meters wide and 30 meters tall.
The project revitalized global shipping routes, enhancing trade efficiency worldwide.
Despite its profound impact on global commerce, the expansion is often overshadowed by newer megaprojects.
Why These Marvels Are Forgotten
1. Overshadowed by Newer Projects
In a fast-paced world, newer, flashier projects often take the spotlight, leaving older achievements in the shadows.
2. Lack of Publicity
Unlike iconic landmarks, many of these marvels were built for functional rather than aesthetic purposes, resulting in less media coverage.
3. Geographical Isolation
Some projects are located in remote or less-traveled regions, limiting public awareness and appreciation.
The Importance of Remembering Forgotten Marvels
These engineering feats deserve recognition not only for their technical achievements but also for their profound impact on society. By studying and appreciating these marvels, we can:
Gain insights into innovative problem-solving techniques.
