At it's most expansive, the Roman Empire was about 5 million square kilometers (2 million square miles). The United States is far larger, at 9.8 million square kilometers (3.8 million square miles).
However, when the Roman Emperor Hadrian (76-138CE) visited Britain in 122 CE, he ordered a stone wall built to protect this more vulnerable northern boundary. Hadrian's Wall stretched across England for over 73 miles (117 kilometers) and was as thick as 10 feet (3 meters). [See list of Roman emperors]. During World War II, the Nazis forced hundreds of thousands of Polish Jews into a small area of Warsaw and contained them with a wall.
