The cathédrale St Jean towers over the Saone river and can be seen from most places in the city. It dominates the old city of Lyon and has a delicious interior which is vast.
Tall columns support richly painted ceilings and beautifully crafted stained glass windows. Don't miss the famous astronomical clock and a copy of the Black Madonna in Częstochowa in Poland.

Place St Jean
This is the Basilique Notre-Dame de Fourvière you're talking about, on top of the hillside, whereas Cathédrale St Jean is the other, older cathedral next to Place St Jean in Vieux Lyon, at the bottom of the hill.
