novilé is a fun digital trail for exploring Lake Gruyère in a totally innovative way.

The Lake tour is divided into 7 walks, which each include between 3 and 5 information signs. What’s more, you can download an app to enjoy activities full of surprises. It will give you all the practical information you need to discover them and you can also use it to take part in a treasure hunt.

……And where there’s a treasure hunt, there’s treasure. So without further ado, let’s get going !

In the time of castles

In the 10th and 11th centuries, minor lords established their authority over part of the Fribourg territory. As a sign of their power, the lords of Pont built their first castle in 1160; this was followed by two other castles, a burg, or rather a small town, and a chapel dedicated to St. Theodore, many times abandoned and many times restored.

July 1948, Lake Gruyère is born

In the 1930s, the electricity generated by the Thusy and Montsalvens Dams was no longer enough to meet the growing demand. Les Entreprises Electriques Fribourgeoises (now Groupe E) planned to build a new impoundment between Treyvaux and Rossens in order to store water and use it rationally according to the seasons. The project was unanimously accepted by the Grand Council in December 1943.

A cliff-scaling bird the size of a large blackbird (16-17 cm/15 to 20 g), the wallcreeper is known as “the butterfly bird”: it has the habit of opening and closing its wings, even while resting, which displays their crimson and purplish colour. It also has an ample flying style with wide, round wings that make it look like a butterfly in flight.

30 million years for a lake

The more or less resistant nature of the different layers of molasse, formed between 30 and 15 million years ago, has shaped the landscape of Lake Gruyère: indeed, the lake is positioned at the foot of the Prealps, on the soft sandstone and marls of the Subalpine Molasse. These rocks’ poor resistance to erosion allowed the glaciers to carve out a vast basin, where the lake is today.
