TV documentary series about re-building Ancient engineering wonders??

[Pioneer]

G'day gents

I am looking for the name of a TV documentary series, which had historians and engineers look at and reconstruct ancient engineering wonders (including weapons).
I recall that some of engineering feats covered -
- Caesar's Rhine Bridges
- Water screws that lifted water to the hanging gardens of Babylon
- Archimedes Claw
- A Trebuchet
- and a couple more which I can not recall :-\

My son is at the age where he is showing interest and curiosity in such things!

Thanks in advance
Regards
Pioneer
