Germany: Bayreuth – Margravial Opera House
Margravial Opera House in the town of Bayreuth was built between 1745-50 in the spectacular baroque style and has been preserved and restored to make it one of the best opera houses in Europe. It was design by the leading theater architects from Italy at the time. Wagner chose Bayreuth as the location for his festival in 1872 and directed on the stage of this opera house (I wonder if 300 years from now Ibiza and the Ushuaia Club will be considered the finest example of “classical” electronic music). The opera house is surprisingly accessible by guided tours even without any performances and you can admire absolutely stunning interior, the stage, and decorations, especially on the ceiling. It is a UNESCO World Heritage Site.
