Martin Gobsch is a puppet maker and stage designer with a small show workshop on the Krämerbrücke in Erfurt. Visitors can watch the puppet carver at work in his small workshop. But there is also a highlight outside the workshop. In 2010, the puppet maker opened a fairytale miniature theater in the shop window of the workshop. The Theatrum mundi consists of 20 individual figures and various scenes that retell the fairy tale of Snow White and the Seven Dwarfs. For one or two euros, the mechanical puppet show comes to life.
