What's the best masterpiece of architecture in the world?

One of them may be the Duomo of Florence in Tuscany, Italy. There are so many though it is hard to pick one.

I agree that it would be hard to select the best one because there are now so many. Plus, it is just a matter of opinion as to which one would be the best. The following search might be a good place to start in finding the best ones, though.

These are just a few links of very different architectural pieces,take your pick,which I am sure is a rather difficult choice.As architecture is unique in so many different ways.:)

I agree with the first poster... the Duomo in Florence Italy is definitely high on my list.

I was there a couple years ago and took some pics... here's a sampling! :)

Enjoy!

Nice pictures. I like it because of all the detail that went into it, incredible workmanship. The Florence Cathedral in your first picture is beautiful too.
