The official Vatican City travel guide was released, aimed at making life easier for pilgrims and tourists, and offering accurate and exhaustive details for scholars and historians.
The General Guide to Vatican City says it's trying to fill the gap created over the 80 years since the Vatican published its first official guide one year after the city-state was established in 1929.
Even though there are many other travel guides out there, "what was still missing was an essential, rigorous work that illustrates" every aspect of Vatican City, the guide's introduction says.
The 447-page paperback was published in English, Spanish, French and Italian.
The 2012 guide packs in colourful photos, maps, contact information and extensive details about the artistic, archaeological, architectural and historical patrimony housed on Vatican City State's 109 acres.
