The St. Nikolai Church in Hamburg was mostly destroyed during air raids in World War II. Approximately 35,000 people were killed during the air raids. The ruins of the church now serve as a memorial to the victims of the war. The church's tower was used to help allied pilots navigate, and it still stands today, almost undamaged.
The memorial at St. Nikolai Church includes a permanent exhibition in the crypt of the ruins that depicts the causes and consequences of the aerial war in Europe. Black and white photos show images of the war and the destruction that came with it. The memorial also serves as a cultural meeting place. Concerts, films, and lectures link events, social issues, and conflicts of the present. Events deal with the German culture of remembrance and lectures on current international politics. Germany's largest glockenspiel was installed here in 1993, and it is sounded at concerts to remember the victims of the war.
Standing at 147.3 meters (483 feet) it is the highest church tower in the city and the fifth highest church in the world. Visitors can take the glass elevator to the observation deck at 76 meters (249 feet) for a panoramic view of Hamburg.
