The Oper am Gänsemarkt was a theatre in Hamburg, Germany, built in 1678 after plans of Girolamo Sartorio at the Gänsemarkt square. It was the first public opera house to be established in Germany: not a court opera, as in many other towns. Everybody could buy a ticket, like in Venice. Most works were in the German language or translated librettos (from Italian).
The building was torn down in 1756, but rebuilt in 1765.
