History

The bishops gradually abandoned Tourbillon because access was difficult and siege warfare had changed. After the final fire, the bishopric lacked funds to repair it, and surviving materials were reused in other buildings.

  1. Around 1297–1307Construction began around 1297 or 1298 under Bishop Boniface de Challant; much of the complex dates to around 1307.
  2. 1373Guichard Tavel acquired the Majorie tower below Tourbillon as the seat of episcopal power; Tourbillon retained defensive and symbolic roles.
  3. 1417The castle was burned and dismantled during the Raron Wars.
  4. 1440–1450Bishop Wilhelm III of Raron rebuilt damaged sections and commissioned a new chapel mural cycle, now displayed in the sacristy.
  5. 1788A fire destroyed the castle, which was never rebuilt.
