The photographers (De Graaf Photographes) have hidden 7 Easter eggs in the panorama, 5 of them are related to the history of Lyon. The visitor can therefore spend some time finding the surprises and discovering the famous monuments of the 3rd biggest city in France, such as the Fourviere basilica (19th century), the Saint-Jean Cathedral (15th century) or the historical courthouse (19th century).

The shooting took place during the winter; the same panorama will be created over the 3 other seasons.
