Aegidienkirche
Hannover, DE
This 14th-century cathedral was built on the site of a former 12th-century Romanesque church and an even older chapel. It was the site of where the reformation began in Hanover. The church was destroyed in an air-raid during the Second World War, leaving only the tower and some walls. Today it stands as a war memorial, featuring a sculpture, dedicated in 1959 and a peace bell donated from Hanover's sister city, Hiroshima, Japan.
