The Gothic Revival Church of St. Nicholas was formerly one of the five Lutheran Hauptkirchen (main churches) in the city of Hamburg. The church lies now in ruins, with only its tower remaining, serving as a memorial and an important architectural landmark. When Hamburg residents mention the Nikolaikirche, it is generally to this church that they are referring, and not the new Hauptkirche dedicated to Saint Nicholas, which is located in the Harvestehude district.
