Royal theatre Dresden
Germany
The Königliches Hoftheater (Royal Court Theatre) in Dresden, Saxony, was a theatre for opera and drama in the royal seat of the Kingdom of Saxony from 1841 and 1869, designed by Gottfried Semper. It was the predecessor of today's Semperoper, and is therefore sometimes called Altes Hoftheater (Old Court Theatre).
