In a city full of spectacularly beautiful theaters, the massive pale-green Estates' still ranks as one of the most awesome. Built in 1783, the Estates' was home to the premiere of Mozart's Don Giovanni, which was conducted by the composer himself. The building, an example of the late baroque style, was reopened on the 200th anniversary of Mozart's death in 1991, after nearly 9 years of reconstruction. The theater hosts mainly dramas performed in Czech but occasionally has performances of Don Giovanni for tourists and also puts on very worthwhile baroque opera.
