oceanicsteam:Forget admiring the technical skill it took to build these things near 2,000 years ago(don’t forget it’s not just a question of building the structures and tunnels, ancient surveyors needed them to continue to slope very slightly downwards at the right angle for sometimes up to 15-20 miles) can we just admire the fact they still stand despite most of them not having received any restoration in 1,500 years.(the notable exception being the Aqua Virgo which was one of the 11 aqueducts that fed Rome which was extensively repaired and modified in the 15th century by Pope Nicholas V and now feeds the Trevi Fountain among others) -- source link
