The Magdeburger Dom was the first Gothic cathedral built in Germany. Its interior is 120 m long and is beautifully lit through the large clear windows. The original medieval stained-glass windows were already destroyed during the Thirty Years’ War. Between 1847 and 1907, all 89 windows of the cathedral were painted to cover 2300 square meters. All these were blown out on 12 September 1944 during the first air raid on Magdeburg.
