This early image shows the view across the ancient city centre of Cologne with the cathedral in the background. Now a UNESCO World Heritage Site and Germany’s most-visited attraction, the present cathedral was begun in 1248 but not finished until 1880. Its two towers weren’t built when the stereoview was taken. The cathedral was damaged during World War Two but has since been restored. The rest of the city centre was almost completely flattened, most notably during a so-called ’1000 bomber raid’ in May 1942.
