Arianna visits Lucca for the first time, and gets some advice from a friend who lives there. Arianna and Eleonora look at the map together to get an idea of how the city is laid out. With its Roman origins, Lucca's urban space was designed with intersecting roads called 'cardos' and 'decumani'.

Mini decides to guide Arianna through one of the main roads of Lucca to the center of the city. It's one continuous road but its name changes several times. Arianna is fascinated by some mysterious numbers appearing on the stones of the pavement.

The best way to get around Lucca is by bike. Arianna rents one and enjoys riding along the amazing walls of the city, still intact after centuries.

There are a lot of interesting places to see from the walls, as Arianna rides around on her rental bike: the botanical garden, a tower with trees on it, and the entrance to a pilgrimage route to Rome.
