Again, I would be surprised in the event there are more per head than England.Per capita- if it is not Italy I will be surprised. I couldn't believe how many were just in Venice.
Having been to Florence, Naples, Venice and Rome; I didn't really notice a lot of churches.
What did strike me about Italy is what a conservative country it is.
By that I mean that when you drive through English towns and villages there are a lot of sporting activities and general recreational buildings/activities for people to meet and socialise. Italy on the other hand seemed to me to be no more than people's homes, and the odd church and school.
There may be a lot of churches in Venice, but when you get into the countryside you don't see many, whereas in England every village has a church, or at least that used to be the case before religion started to die and recently churches have been shut down or turned into a building for some other use.
