On our last day we went for a great walk to the south.
We stopped by the new cathedral again. While we were admiring the door, trying to find the symbols of the city - the astronaut and the gargoyle eating an ice cream - a local explained us the entire facade and asked if we wanted him to go with us to the university entrance. Very skeptically, we accepted and he told us the very long story of the door, the frog and the typography that we can see written on the university’s walls.
After that, we went to see the Art Noveau and Art Deco museum, with its amazing facade of glass.
And ended the day next to the river, appreciating the view to the city and its great cathedral towers.
