The app contains two maps: one of the Dante plaques and the other of all the remaining sights. To access the first, simply select the orange circle (see below) on the menu of Dante plaques.
To access the other, simply choose “Near me” from the main page. The classes of places on this second map are color-coded for your convenience. Markers are blue, Churches are red, Depictions of Dante are purple and so on.
Lastly, when you select a pin on a map, you’ll see a text box open that contains the name of the point of interest and its street. If you click on it, you’ll be taken to the document in the app that explains that point’s historic and literary importance.
