Roman concrete, or opus caementicium, was incredibly durable and even self-healing with seawater. Modern engineers still study its unique chemical makeup.
3. Aqueducts – Ancient Persia and Rome

The “Baghdad Battery” is a mysterious artifact believed by some to be an ancient galvanic cell. Made with clay jars, copper, and iron, it may have generated low-voltage electricity.
7. Dentistry – Ancient Egypt
