#5: The Kiel Canal – 61 Miles

The Kiel Canal in Germany is one of the busiest artificial waterways in the world, stretching 61 miles and connecting the North Sea to the Baltic Sea.  Completed in 1895, it shortened the route for ships traveling between these bodies of water by 280 miles.  Its efficiency and safety have made it a preferred route for commercial shipping.  The canal is lined with scenic views, attracting tourists and photographers.

#6: The Welland Canal – 27 Miles

Part of the St. Lawrence Seaway in Canada, the Welland Canal stretches 27 miles and bypasses the Niagara Falls, connecting Lake Ontario and Lake Erie.  Completed in 1932, it is a critical link in the Great Lakes shipping system.  The canal’s locks lift ships over 300 feet, enabling smooth navigation between the two lakes.  Its history includes tales of engineering breakthroughs and its role in fostering economic growth in the region.

#7: The Corinth Canal – 4 Miles

The Corinth Canal in Greece, though only 4 miles long, is a remarkable engineering achievement.  Cutting through the Isthmus of Corinth, it connects the Aegean and Ionian Seas.  Completed in 1893, the canal’s steep limestone walls and narrow passage make it a dramatic sight.  Its history dates back to ancient Greece, with early attempts by rulers like Nero to construct it.

#8: The Göta Canal – 120 Miles

The Göta Canal in Sweden spans 120 miles, connecting Gothenburg and Stockholm through lakes and rivers.  Completed in 1832, it features 58 locks and is a confirmation to Sweden’s industrial ingenuity.  Today, the canal is a popular tourist destination, offering picturesque views and a glimpse into 19th-century engineering.

#9: The Illinois Waterway – 336 Miles

The Illinois Waterway, a 336-mile system of rivers and canals, connects Lake Michigan to the Mississippi River.  Completed in the early 20th century, it is a vital corridor for agricultural and industrial goods.  The waterway’s history is tied to the economic development of the Midwest, serving as a lifeline for trade and transportation.

#10: The Erie Canal – 363 Miles

The Erie Canal in New York spans 363 miles, connecting the Hudson River to Lake Erie.  Completed in 1825, it was a groundbreaking project that transformed transportation and commerce in the United States.  The canal’s success inspired a wave of canal-building across the country.  Anecdotes of its construction include the use of innovative tools and techniques that set new standards for infrastructure projects.

The largest canals in the world are not just impressive engineering achievements but also vital lifelines for trade, transportation, and cultural exchange.  From the ancient Grand Canal of China to the modern marvel of the Panama Canal, these waterways have shaped history and continue to connect the world.  Preserving and celebrating these canals ensures their stories and significance endure for future generations.
