Berlin Cathedral
In 1747, Frederick II had architect Johann Boumann the Older build a cathedral next to the Lustgarten, replacing an older version situated south of the royal palace and dating back to 1536. In 1817 Schinkel redesigned Boumann's building. It was demolished in 1893.
Today's monumental structure was erected between 1894 and 1905 to plans by Julius Raschdorff and his son, Otto. This outstanding example of religious architecture in the latter part of the 19th century contains elements of Roman baroque and Italian high renaissance.
The cathedral was badly damaged in the Second World War. However, while the adjacent royal palace was demolished for ideological reasons, the cathedral ruins were left untouched. The church authorities in the GDR even managed to begin restoration work on this vast building in 1974. With financial help from the Protestant Church in the Federal Republic of Germany, a somewhat simplified restoration of the exterior was completed in 1981.
The interior with its eight ceiling mosaics, the imperial staircase, and the crypt were restored between 1984 and 2002. About 100 coffins found in the crypt have been on display since 1999 - including those designed by Peter Vischer in 1530, and the magnificent coffin for Frederick I designed by Andreas Schlüter. Since the early 1990s, services and concerts have once again taken place in the cathedral.
