G.C.S.E Original Writing The history of the canals Canals have been around for many years. The earliest that have been discover so far was in Iraq the archaeologists estimate that the remains are 6,000 years old. These waterways were fairly short. This was because locks had not been invented. The Chinese invented the first lock system almost a thousand years ago. This can still be seen in the modern ay. The first people to bring the canal system to England was the Romans. They build lengths of simple, single level canals. Leonardo da virci designed and built the pound lock for the duke of Milan. The Llanguedoc Canal were the locks would be used was completed in 1681.This canal connected the Mediterranean Sea with the Atlantic ocean and saved ships a voyage of over 1,600km.
