On the St-Maire Castle esplanade, you can see: A part of the city, Lake Geneva and The Jura Mountains. From this esplanade, situated on the Cité hillside, you can see not only part of the city but also the lake and the Jura Mountains.
To your right, a large arterial road heads into a hollow. It follows the initial course of the River Louve, which is now buried, but which over time hollowed out a valley in this spot. Together with its “cousin”, the Flon, this river created the Cité hillside by eroding the molasse, a grey rock used to build St. Maire Castle and the cathedral. Go from the castle courtyard to the cathedral. 5 mins.
