After visiting ETH-Zürich I rode the train to Lausanne,
located across the lake from Geneva in far west Switzerland,
and where the common language is French. I spent the afternoon
and most of the evening exploring the old town district (both
the social Centre-ville and the older Vieille Ville), and in
particular the Lausanne Cathedral. After dinner I briefly walked
down to the the lakefront area (Ouchy) along Lake Geneva.
