Adjacent to the church, the Lausanne History Museum, converted from the bishop's residence, was the only audience I entered (CHF4, free of charge with Swiss Pass). The bearded administrator was intimate enough to open the light show for me (the theme is historical change) of this Lausanne city model, and I had to watch it for 20 minutes in my seat. The collection of cultural relics was concentrated after the Middle Ages, with more home furnishings and art collections at that time, because the background of the Reformation was not yet understood, and it was only possible to see the flowers.
