Greece and Rome
The Romans built 250,000 miles of roads. They were built out of big concrete blocks. This led to the building of the roads we have today such as highways. The Romans also built aqueducts. Aqueducts were elevated water systems that brought water to Rome from faraway streams and lakes. Today we have plumbing systems that are a more advanced version of Roman aqueducts.
The Greeks invented three types of columns. Today there are many buildings with pillars and columns like the buildings in Washington DC.
