I start one of my favorite walks with God in the early morning, but any time will do. By 7 A.M. I have begun a walking tour of the foremost churches of Florence built by one of the religious order that flourished during the 13th and 14th centuries. Each one radiates from Santa Maria dei Fiori, referred to as the Duomo, so I usually start out at this epicenter that is the soul of Florence. Regardless of the route I take, I figure I cover about five miles on this two hour city circuit, which includes time to take photos of the facades and to stop for a cappuccino or two.
