Cube 521 is a modern cultural centre in Marnach, the largest village in the commune, named after the coordinates of its location. The building houses an auditorium seating around 300 people and hosts concerts, theatrical performances, and community events throughout the year. It is a striking piece of contemporary architecture set against the otherwise rural Ardennes backdrop.
The programme tends toward classical music, jazz, and folk, drawing audiences from across the canton of Clervaux. If you are passing through the area, it is worth checking what is on — the venue punches well above its weight for a village of this size, and an evening concert here is a more memorable experience than most of what the tourist circuit in Luxembourg offers.
