This here is the Basilica of San Petronio in Bologna, which sits at one end of Piazza Maggiore, the main square. It is the fifth highest church in the world. The work of many builders and architects, it was started in 1390. It looks unfinished, doesn't it?
Well, it is and it isn't. You see, the legend goes that when they were building it they all of a sudden ran out of money. That's not what happened.
The project was so grand in scope and ambition that too many builders and far more famous architects got involved and the façade was never completed. Everyone wanted to participate in the making of this communal space. It was used by the city for many centuries and not exclusively for religious ceremonies; the place was large enough for public meetings and to stage court cases. Believe it or not it became property of the Dioceses only in 1929.
I would venture to state that it does not matter that the façade is not perfect. I would be willing to bet that all those famous architects and builders might be just as proud of their work today. This is an inspiring place and it pulses with activity.
Every person who ever visits Bologna stops in front of this church in awe. It's weird and fascinating at the same time, worth photographing and learning about. It's not perfect, but it sure is remarkable.
