Challenges are much too obvious (word translation, what is the first letter of ..., or answers which are given in the question...)

The mission: Your story in Paris

A mysterious historian, Professor Émile Varenne, sends you an urgent message: an old Parisian secret has been hidden across Île de la Cité for centuries. 

To uncover it, you must follow symbols left in plain sight: a guardian, a bridge, a zero point, three gates, old streets, royal light and a king on horseback. Each clue reveals a fragment of the city’s memory. Reach the Pont Neuf before the trail disappears again.
