A church has stood here since 1536, but this enormous version dates from 1905, making it the largest 20th-century Protestant church in Germany. The royal Hohenzollerns worshipped here until 1918, when Kaiser Wilhelm II abdicated and left Berlin for Holland. The massive dome wasn't restored from World War II damage until 1982; the interior was completed in 1993. The climb to the dome's outer balcony is made easier by a wide stairwell, plenty of landings with historic photos and models, and even a couple of chairs. The 94 sarcophagi of Prussian royals in the crypt are significant, but to less-trained eyes can seem uniformly dull. Sunday services include communion.
