(St. Stephen's Cathedral) Wien, Picture 21, Edited Version, Austria, 2013

Here's a shot of the later, gothic spire, also called the Steffle. It was added over 65 years between 1368 and 1433. It doesn't look it (maybe because it's also thicker than many steeples), but it is actually 136 metres, or 449 feet, tall. That makes it the 13th tallest church tower in the world, which is especially impressive when you consider how old it is, and might explain why it took 65 years to build. At the time of construction (and I haven't researched this thoroughly so correct me if I'm wrong) it would have been the second tallest in the world, and the one tower which was taller, on Lincoln Cathedral, collapsed in a storm in 1549, suggesting that the engineering was not as good (after all, England never has had the same level of storms as many other countries). Architecturally (in the artistic sense), however, Lincoln is well-regarded, and survives, albeit without its original 3 spires.
