Den Grå Hal is an unusual entertainment venue located in the equally unusual hippie area of Christiania. Once a riding arena, way back in 1891, this space was later converted to serve as a community center for the people of Copenhagen. Don't expect to find aristocratic snobs attending world orchestras and ensembles here; Den Grå Hal has hosted more magical events the like Christmas Gala for the homeless. A visit would be recommended especially if one seeks to witness the alternative entertainment lifestyle.
