Martin Luther visited Dresden in 1516 and 1517. In the castle chapel (today a theater) he preached before the Saxon royal court. Indeed, Saxony was the first state that officially introduced the Reformation, coming in two steps, in 1537 and 1539. The first Protestant religious service in Dresden took place with the Kreuz Choir in the city's Kreuz Church.
Masterworks of the most famous of the reformation painters, Louis Cranach, can today be found in the Old Masters PIcture Gallery. Today, the cultural legacy of the Reformation can be seen in the majestic Church of Our Lady. The Semper Opera House stands for Dresden's rich musical tradition.
