Theatres Romains de Fourviere

These are the oldest Roman theaters in France, built right into the Fourvière hillside starting in 15 BC. The Grand Theatre could hold 10,800 spectators and still has its original stone seating rising up the slope, while the smaller Odeon next door hosted intimate music recitals. What makes them special isn't just their age: they're free to explore and the view from the upper rows spans the entire Rhône valley on clear days.

Walking through feels like stepping onto an ancient film set. You can climb right up to the top rows where Roman citizens once sat, run your hands along 2,000 year old stone seats, and stand on the stage where actors performed for emperors. The theaters are cut directly into the rock face, so you're walking through genuine Roman engineering. Summer evenings bring the Nuits de Fourvière festival, when these ancient stones come alive again with opera and concerts.

Most people rush through in 20 minutes, but you should spend at least an hour here. The attached Gallo Roman Museum costs EUR 7 and houses the famous Claudian Tablets: actual bronze speeches by Emperor Claudius, who was born in Lyon. Skip the museum if you're tight on budget, the theaters themselves are the real draw. Come in morning light for the best photos and fewer crowds.
