The original Kaiser Wilhelm Memorial Church on the site was built in the 1890s. It was badly damaged in a bombing raid in 1943. The present building, which consists of a church with an attached foyer and a separate belfry with an attached chapel, was built between 1959 and 1963. The damaged spire of the old church has been retained and its ground floor has been made into a memorial hall. The Memorial Church today is a famous landmark of western Berlin, and is nicknamed by Berliners 'der Hohle Zahn', meaning 'The Hollow Tooth'.
Kaiser Wilhelm II decided to name the church in honor of his grandfather Kaiser Wilhelm I. The foundation stone was laid on March 22, 1891, which was Wilhelm I's birthday. The competition for the design was won by Franz Schwechten who planned for a large church to be built in Romanesque Revival style, including 2,740 square metres of wall mosaic. The spire was 113 metres high and the nave seated over 2,000 people. The church was consecrated on September 1, 1895. By this time of the consecration the entrance hall in the lower section had not been completed. This was opened and consecrated on February 22, 1906. In the Second World War, on the night of November 23, 1943, the church was irreparably damaged in an air raid. The church was largely destroyed but part of the spire and much of the entrance hall survived.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
