A silent wonder near the city of Patara in Turkey, the Delicca Canal stands as a testament to the extraordinary engineering skills of the Romans. Not only did this canal provide water across the mountains and valleys, but it also used reverse siphon technology to ‘lift’ water up a 10-meter-high stone wall!
Each stone in this structure weighed about 900 kilograms, and was carved so precisely that not a single drop of water escaped when it was fitted together. Maintenance was even considered, with some stones having holes on the top that could be cleaned, and some blocks could be removed for repairs.
When the structure was damaged by an earthquake in 68 AD, Emperor Vespasian had it repaired. No taxes were imposed on the locals for this work. Building an infrastructure using only stone, talent, and science, without steel or cement, is like a living lesson in engineering.
