Waldbühne (German: Woodland Stage or Forest Stage) is an amphitheatre in Berlin, Germany. It was designed by German architect Werner March in emulation of a Greek theatre and built between 1934 and 1936 as the Dietrich-Eckart-Freilichtbühne (German: Dietrich Eckart Open Air Theater), a Nazi Thingplatz, and opened in association with the 1936 Summer Olympics. Since World War II it has been used for a variety of events, including boxing matches, film showings and classical and rock concerts. It seats more than 22,000 people. Every year the Berliner Philharmoniker comes here to give a stunning open air concert. In 1996 Claudio Abbado conducted the orchestra. He invited singers Bryn Terfel, Sergei Larin and Angela Gheorghiu to sing Verdi arias. On the program: Verdi - Overture from Nabucco, Duet 'Et lui...' from Don Carlos, Fire Chorus, Jago's Credo, 'Gia nella notte....' from Otello, Triumphal March from Aida and Bellini - 'Eccomi...' from I Capuleti e i Montecchi.
