Memorial to peace and reconciliation
In 1890 Kaiser Wilhelm II ordered the construction of the Memorial Church in honour of his grandfather Kaiser Wilhelm I. It was destroyed in a Second World War bombing raid, and since then has stood as a tribute to peace and reconciliation. Instead of pulling the church ruins down, the bombed out torso of the tower was integrated into the new building that was built around it. Known as the "hollow tooth", it is the symbol of Berlin's determination to rebuild after the war.
