How much of the aqua Claudia is left?

The Aqua Claudia, an ancient Roman aqueduct completed in 52 AD, has largely fallen into ruin over the centuries. While significant sections still remain, particularly in the outskirts of Rome, much of the original structure has been damaged or destroyed. Today, parts of the aqueduct can be seen in various locations, but only a fraction of its original length and height are intact. Preservation efforts continue to highlight its historical significance.
