St. Michael's Church (German: Hauptkirche Sankt Michaelis, colloquially called Michel, German pronunciation: [ˈmɪçəl]), is one of Hamburg's five Lutheran main churches (Hauptkirchen) and the most famous church in the city. St. Michaelis is a landmark of the city and it is considered to be one of the finest Hanseatic Protestant baroque churches. The church was purposely built Protestant unlike many other Hamburg churches which were originally built by Roman Catholics and were converted to Protestantism during the Reformation. It is dedicated to the Archangel Michael.
