While planning to build a house for renting on a plot of land he owned, Léonard Gianadda, an engineer, discovered in the spring of 1976 the remains of an ancient Celtic temple, the oldest of its kind in Switzerland.
Shortly afterwards, on 31 July 1976, his younger brother Pierre tragically died in the aftermath of a plane crash while seeking help for his fellow survivors.
Léonard, who was very attached to Pierre, decided to create a foundation to perpetuate his memory. He erected a cultural centre around the temple, which would bear the name of his brother...
It was inaugurated on 19 November 1978, on the very day Pierre would have celebrated his 40th anniversary
