The roof truss of the cathedral was built about 30 years before the construction of the Eiffel Tower, and is one of the most important examples of early iron construction. When it was installed in 1860 over the vaults of the nave and transept, it was at first controversial - many thought that the roof truss of the cathedral had to be constructed of wood, as in the Middle Ages.
Edit:
Also worth a visit is the Ulm Minster. Here the original timber frame was replaced by an iron roof truss in 1890, a few years after its completion.
Yes. I've been to Ulm Minster. I had wanted to visit having seen the enormous tower from a distance many times so eventually I decided to stay in Ulm on my way to Austria or wherever it was. I remember the visit; it rained constantly and the Danube overflowed and there was flooding! I didn't want to leave my GPS in the car so put it in my pocket; it got so wet it was destroyed and then I had to navigate the rest of the trip with paper maps. Heaven forbid
