This was the first postcard of a UNESCO site that I received through the website postcrossing . It was sent by Dorothee

Cologne Cathedral

Construction of Cologne Cathedral commenced in 1248 and was halted in 1473, leaving it unfinished. Work restarted in the 19th century and was completed, to the original plan, in 1880. It is 144.5 metres (474 ft) long, 86.25 m (283.0 ft) wide and its towers are approximately 157 m (515 ft) tall.The cathedral is the largest Gothic church in Northern Europe and has the second-tallest spires(after Ulm Minster. See info-box below.) Its two huge spires give it the largest façade of any church in the world. The choir has the largest height to width ratio, 3.6:1, of any medieval church. - in: wikipedia
