Formerly a prison workshop, the building now houses a theater named after Robert Krieps, the minister of justice and culture who initiated the creation of neimënster. The former workshop - formerly known as the Tutesall - houses a 283-seat theater equipped for performing arts, film and lecture projections. The comfortable seating and dark velvets, the omnipresence of wood, and the high ceiling give the room a twilight aura. A refreshment bar in the basement allows receptions to be held and offers the possibility of quenching one's thirst during the intermissions.
