Some contributions that the Romans gave to us are the bridges, roads, Roman Numerals, Julian calender, public bathhouses, and beautiful architecture, such as cement arches.
The Romans gave the bridges and roads so they could travel faster and easier. They also passed on the Roman Numerals to be used as numbers. Believe it or not, we use the 365 Julian calender today, which was created in the rule of Julius Caesar. Public bathrooms came from the Roman invention of the bathhouses .
Without the Romans, we wouldn’t have the Colosseum or any of the famous artwork that they did. They also invented cement and the cement arches as an advance to their art and architecture.
