Which are the oldest bridges in the world?
That's really interesting. Are there any other ancient bridges that you know of?
Yes, there are many others! The Kallanai Dam in India, which was built in the 2nd century AD, is considered to be one of the oldest known dams and is still in use today. There’s also the Aqueduct of Segovia in Spain, which was built in the 1st century AD and still stands as a testament to Roman engineering.
