What was romes achievement?

Answer 1

It is a matter of opinion. Great achievements of Roman engineering were the stone-paved roads, bridges which were based on sequences of arches and could cross much wider rivers and valleys than before, the aqueducts, the hypocaust (an underfloor heating system for houses) and fortification systems. With regard to weapons, the Romans greatly improved on the ballisata, a crossbow-like catapult which they originally adopted from the Greeks. The Roman also had good drainage and irrigation systems for agriculture.
