Bisse d'Ayent

It takes its source at the Tseuzier reservoir and irrigates vineyards and meadows in the municipalities of Ayent and Grimisuat.

Built in 1442, it takes its water directly from the Liène river, below the Tseuzier dam (1777 m above sea level).

At the time, the bisse passed through wooden canals fixed to the vertical wall, several hundred meters above the ground.

Near the entrance of the tunnel is a hammer which allowed the watchman of the bisse to know if the watercourse continued to flow normally.

In 2019, the Swiss National Bank (SNB) unveiled the design of the new series, whose banknote of 100 francs represents on its back the passage of Torrent-Croix of the Bisse d'Ayent.
