Maria Gloriosa

This was the largest church bell in the world when cast in 1497 by Gerard van Wou.
This bell is considered the most beautiful-sounding bell in the world!

That's one of the reasons of the nice sound of bells (the overtones) and the shape of the bell developed during the Middle Ages as I understand it creates that sound

Doppler it is!
