At the Hermann Hesse Museum in the south of Switzerland, where Hesse moved in 1919. Charming Medieval and Renaissance Italian-style neighborhood high in the hills overlooking the valley that overlooks Lugano. Here he wrote Siddhartha (1922), Steppenwolf (1927), The Glass Bead Game (1943).
I have a future episode on Siddhartha coming out in the Philosophers. Explained series.
