This is the Ulm Munster. The tower is the tallest church steeple in the world. Construction of the Munster started in 1347 and was completed in 1880. Back in the 1300's, money for construction ran dry about a third of the way through the project, so a temporary roof was erected. In the early 19 century, people in Ulm decided that the temporary roof was too ugly and that the church should be finished. It is now a fifth of a kilometer high. There are steps most of the way to the top, and I managed to climb all 768 of them. There's a noticeable temperature difference, but the view's amazing.
