It's more than 100 meters high

I took this photo in Milan, Italy by my iPad mini. The photo shows Duomo di Milano  (English: Metropolitan Cathedral-Basilica of St Mary of the Nativity or being simply called Milan Cathedral). It's a stunning Gothic Cathedral and is more than 100 meters high and 100 meters wide. It was a little too hard to take a photo of the whole building from the ground level, so this is just an example. When you look up the Gothic Cathedral from the square, the cathedral looks like this. Huge, isn't it? It was really a magnificent view.
