Calw, one of the Black Forest's prettiest towns, was the birthplace of Nobel Prize-winning novelist Hermann Hesse (1877-1962). He was born at Marktplatz 6, now a private home. The town's market square, with its two sparkling fountains surrounded by 18th-century half-timber houses whose sharp gables pierce the sky, is an ideal spot for relaxing, picnicking, or people-watching, especially when it's market time.
