Switzerland's Great Cities - S5.E5

Focusing on Switzerland's often-overlooked urban charms, we explore lakeside Luzern, cobbled Bern, spire-filled Zürich, and sophisticated Lausanne. We'll enjoy eye-opening art, from Chagall and Klee to the works of asylum inmates. We'll ring a very big bell high up in a church spire, float down a rushing river, and ponder Switzerland's pragmatic drug policies and hidden underground arsenals. And it's all before a backdrop of stunning natural beauty.
