The Romans borrowed and adapted ideas from the Greeks as well as the Etruscans. Greek architecture was one important influence on the Romans. As you remember, the Greeks built marble temples as homes for their gods. ... The Romans also used concrete to build huge stadiums like the Colosseum, where gladiators fought.
The main way Greek civilizations influenced Roman culture is religion. The Romans largely adopted Greek religion, but there's some other things like there social structure, art, literature, science, clothes etc. Hope this helps!
