The Dom in Cologne

The Cathedral in Cologne has an amazing story. Started in 1220 or so, it was abandoned in the middle of the 16th century, and then taken up again in 1842.
 

Here, I have snapped it with my iPhone 4; superimposed is an etching on glass of the scene in 1842, when the construction was taken up again. Note the crane on the left. The cathedral was finished using the best 19th century methods. The roof is supported by a steel frame.

In the foreground is an excavation of the old Jewish quarter. It will be enclosed by a brand new Jewish museum.
