Bonjour et bienvenue chez Lyon! Are you ready to enroll in a quest of mysteries and dark secrets? Then, take your croissant and go to the Montée du Gourguillon, a vintage street of the hill of Fourvière that earned its place in the UNESCO Heritage list. This hill road used to be the only link between the Roman city and the riverside districts. Legends say that in the early 14th century, Pope Clement was crowned in the upper town. Due to some unforeseen circumstances, on his way down, his party was partly buried under a falling wall. The Pope's crown fell and a sizable diamond was lost... Some people are still looking for it today, but only a true explorer can find it. So, look around you to answer the question and find the diamond!

Now we are headed towards the Eglise Saint-Just, a church in Lyon that will lure travellers to it through the power of God, of course, but also through its impressive architecture that needs to be admired. But who was Saint Just? He was a well-known bishop, but it is said that he abandoned the episcopate and left in exile in Egypt, following some tragic circumstances which involved a maniac in the doors of his cathedral. Whether you are a saint or sinner, you need to investigate this case, answer the question and advance to your next destination.

On a not-so-sumbre note, welcome to the Loyasse Cemetery, created in the early 19th century to cope with the increase in the urban population. It is considered the “cemetery of the rich” and it is the burying place of the great Lyon families, as well as many of the names that have marked the history of the city. You don’t need to be scared! The funerary architecture that we find in Loyasse is characterized by a great diversity of styles and for good reason, the owners of the spots are free to manage and construct them as they see fit. Check your surroundings and solve the challenge which hopefully, is not buried too deep!

Congratulations! You haven’t been scared so far and now you are about to discover the last mystery that revolves around the Cathedral Saint-Jean-Baptiste de Lyon, the majestic crown of Old Lyon. An impressive mix of Roman and Gothic styles, Saint Jean Cathedral stands out from the crowd in the cobbles of Vieux Lyon, chiming its bells to welcome visitors through its oak doors. As a tradition that dates back to the 17th century, on 8th of December, Lyon holds an annual Fête des Lumières (Festival of Lights), the cathedral playing a starring role, with vivid projections lighting up the main façade. But one place was not lightened enough, as it seems, and you need to discover it in order to call yourself a true Questo explorer!
