The seat of the world-famous Berliner Philharmoniker orchestra, currently led by Sir Simon Rattle, is one of Germany’s finest post-War architectural achievements. The exterior recalls a circus tent, while the pentagonal concert hall is arranged with a central podium for the orchestra and galleries for the audience around all sides. Free lunchtime concerts Tuesdays 1pm. Guided tours offered daily at 1:30pm (except Jul and Aug). €5/3.
