1. Climb The Notre-Dame de la Garde
It is one of the absolute Marseille things to see. This basilica is built on a hilltop and gives a magnificent vista of the city below from its balconies. From here you have the sea view of the Old Port and the Mediterranean Sea.
The visuals are great so it's worth the effort of climbing the steep slope. The views around it are stunning along with the homely feeling that comes with this beautiful area.
The best part is that you can pay by card for your candle to pray. Besides you can also learn about the culture, history, and architecture of Marseille and see symbolism from all over Europe.
