Earlier this week Pope Benedict announced his retirement and mentioned that he would be spending some time at the Pontifical Palace in Castel Gandolfo. If you don't know the Castelli Romani or the Alban Hills, the palace is part of interesting Lazio territory whose rich, volcanic soils have attracted settlers and winemakers for many, many years. Traditionally, regular folks as well as Popes have come here to escape the summer heat of Rome. They wander the streets of the medieval towns, enjoying views of the lakes as well as of Rome, they sit at long, communal tables drinking happily from carafes of Frascati wine, and they hike to sacred spots on top of mountains. It's quite an appealing bit of Italy, so we've made a map and guide to introduce it to you: Castelli Romani Guide.
