About this photo:
This is the tower of the old church (Olde Kerk) in Delft, and it is leaning! The church was started sometime around 1200 AD, and the tower was built later on. The tower was completed in different phases throughout time- you might notice that the spires at the top are properly vertical, while the tower section below leans.
I believe the story goes that the tower started to lean after about half of it was built. After the leaning stablilized, construction of the spires took place and they were built straight up.
It is a beautiful structure inside and out. Recent restoration work (including addition of intricate and massive stained glass windows) has been done, and it is a sight to see!
I only wish I had a better camera at the time.
