This book is meant to provide a tour of some of the more important and interesting churches and other Christian-oriented sites in this city of churches. It is not an all-inclusive guidebook; I do not include restaurant, hotel or transportation information (except as reference points for the various sights near Metro stations). You should augment this tour guide with other Italy and Rome guides from reputable authors and publishers. While detailed walking directions and some maps of the important areas on the tour are included, a detailed map of the city is recommended.
