The Romans built some mighty acqueducts in Spain and the Spanish retained the engineering and built some in the United States in my hometown of San Antonio.

One of them, over 200 years old, still carries water to the surrounding area. Here are a couple of references.

I never knew the Romans built San Antonio.
