Valentin-Volkssänger-Musäum, Museum of comedy and folk singing in Altstadt-Lehel, Munich, Germany

The Valentin-Volkssänger Museum is housed across multiple floors within the medieval Isartor tower and displays artifacts and memorabilia from German comedy performers. The rooms present personal items, photographs, and film archives documenting the early careers of these entertainers.

The museum opened in 1959 and honors Karl Valentin and Liesl Karlstadt, who shaped German comedy in the early decades of the 20th century. Their performances established new forms of entertainment that influenced Munich audiences for generations.

The museum's 2007 exhibition on Bavarian folk singers, curated by Andreas Koll, traces the tradition that shaped Karl Valentin's stage persona. In the Turmstüberl on the third floor, musical and cabaret performances still take place; the café is part of the museum concept and can only be reached with a museum ticket.

The museum reopened in July 2026 after renovation of the Isartor; the city invested 2.65 million euros in fire protection, electrics, ventilation and heating. No step-free access was installed because of heritage-protection rules, so the tower stairs remain the only way up. The Turmstüberl café on the third floor can only be reached with a museum ticket.

The entrance sign grants free admission to "99-year-olds accompanied by their parents". Inside, visitors can find the nail on which Valentin hung his carpentry career when he became a comedian, and a fur-lined winter toothpick. The collection also holds the last cane used in Bavarian schools.
