The Heimathaus Kobersdorf is a folk museum located in a former customs house. It presents the history of the market town of Kobersdorf and its districts Oberpetersdorf and Lindgraben. The exhibition includes six rooms with over 80 exhibits, including agricultural tools, household items, equipment, textiles, and rural furniture, showcasing rural life from past centuries.
A particular focus is on the history of the former Kobersdorf estate and the centuries-long coexistence of the Catholic, Protestant, and Jewish populations. Other topics include the Kobersdorf mineral water "Waldquelle" and the Kobersdorf castle games. The Heimathaus was renovated in 2014 and officially opened in 2015. It is open to visitors from April to October by prior appointment or on the performance days of the castle games.
