Paris' Roman past can be found in the Latin Quarter

Imagine a prosperous city of about 8,000 people built on a small hill next to a wide river, surrounded by forests and marshes. The streets follow a typical Roman grid plan with a forum, baths and amphitheatre.

Sound familiar? Probably not, but if you have ever strolled along boul. St. Germain or rue de la Sorbonne, you have walked these same streets, only about 1,800 years later.
