The Kellertheater im Vogelsang is a small theatre that dates back to 1969. It was established by the cabaret "Chyybäderli" from Uri. These people have also founded the association Kellertheater im Vogelsang.
Events of miscellaneous styles take place in two old basement vaults. The choice ranges from everything between the theatre for children and the musical event for adults. There are about 20 people in the team, which all volunteer their time. The staff is splitted up in work groups (children's theatre, theatre, music and management), who engage the artists and organise the particular event. New staff members are welcome at any time and can get in touch with the team at the indicated address with immediate effect. The season lasts from around September until June during which three programmes including eight to ten events are being showed. The operation of the theatre is financed with the generated money by selling the entrance tickets and drinks/food on the one hand, and with the money donated by the canton, the municipality of Altdorf, the sponsors and with private donations on the other hand.
