Königsberg Cathedral (Russian: Кафедральный собор в Калининграде, romanized: Kafedralny sobor v Kaliningrade; German: Königsberger Dom) is a Brick Gothic-style monument in Kaliningrad, Russia, located on Kneiphof island in the Pregolya river. It is the most significant preserved building of the former city of Königsberg, which was largely destroyed in World War II. Dedicated to the Virgin Mary and St. Adalbert of Prague, it was built as the see of the Prince-Bishops of Samland in the 14th century. Upon the establishment of the secular Duchy of Prussia, it became the Lutheran Albertina University church in 1544. The spire and roof of the cathedral burnt down after two RAF bombing raids in late August 1944; reconstruction started in 1992, after the dissolution of the Soviet Union.
