Opera in Hamburg dates to 2 January 1678 when the Oper am Gänsemarkt was inaugurated with a performance of a biblical Singspiel by Johann Theile. It was not a court theatre but the first public opera house in Germany established by the art-loving citizens of Hamburg, a prosperous member of the Hanseatic League. (Wikipedia)
