The top image is a crop of the original photo. The second one is the actual photo. Note the renovations going on. Its something to be contended with when traveling to lovely locations, such as scaffolding up one side of a church spire!
The tower was first built in the years 1218-20 as part of the city's defenses, a town at that time. The tower was burnt down at one time and been renovated. Its been used for storage and once even served as an air-raid shelter, though I don't see what good would come of that if a bomb ever hit!
