You can pass by not remarking the Opera House. From outside it is very simple, inside is beautiful. They built it after the Italian Opera Houses. This is a very old house one of the first in Europe. It was opened in 1793.The king's loge is extraordinary, Giovanni Appiani Italian master made the decoration.
What a surprise this was ! The theatre is a gem, excellent acoustics and the looks of a real European opera hall. We attended Rossini La Cenerentola a relatively less known opera. It was a real delight. Highly professional.
