On the 29th of October, 1787, Mozart’s opera Don Giovanni premiered at the Estates Theatre in Prague.
The theatre in 1797
The opera was commissioned after Mozart made a successful trip to Prague earlier the same year.
Originally intended for a October 14 debut, it was not ready in time, and so the schedule was reorganised.
The opera was an immediate success, as Mozart was highly popular in Prague.
(A side note: I have seen this opera performed at the original theatre. 🙂 )
