1. Berlin Cathedral
Berlin Cathedral dominates the northern end of Museum Island with its green copper dome rising 98 meters above the Spree River. Built between 1894 and 1905 under Emperor Wilhelm II, the cathedral replaced earlier structures dating back to the 15th century. It serves as the largest Protestant church in Germany and contains the Hohenzollern crypt, where over 90 members of the Prussian royal family rest in ornate sarcophagi. The interior features elaborate mosaics, stained glass windows, and a massive pipe organ with 7,269 pipes. Visitors can climb 270 steps to the dome walkway for views across Museum Island and the city center. The cathedral suffered heavy damage during World War II bombing raids and remained in ruins until restoration completed in 2002. The baptismal and wedding chapel survived relatively intact and retains its original decoration. Sunday services feature organ concerts that showcase the instrument's full range. The crypt tour requires a separate ticket from the main church visit.
