The Map of the Station Churches is fully interactive if you click on the little square in the top left corner of the map. It will identify and locate the church by highlighting it on the map (although the little white halo is a bit hard to see if you don't know where to look) and giving you a link to the Pontifical North American College (PNAC) for additional information on the church. It will also allow you to zoom in to see what other places of interest are around the church and may give you links to more information about those sites.
