Which Italian architectural construction is called "Duomo"?

And in spirit and truth! because the Bible says those who worship God must worship Him in spirit and in truth!

Pic gives it away! if u know how those medieval and gothic churches looked like! yeah I know didn't look so good or like a church! to pray to God! looks more like somewhere to entertain satan! but hey God is wherever u are as long as u are praying to Him with a whole heart!

I've not been to the cathedral

the picture is the clue, thanks
