The transportation system in Vatican City, a country 1.05 km long and 0.85 km wide,[1] is a small transportation system with no airports or highways. Given an average walking speed of 3.6 km/h,[2]Vatican City can be crossed in 20 minutes or less. Thus, much of the infrastructure in the Vatican consists of St. Peter's Square itself, hallways and aisles in the basilica and surrounding buildings, and walkways behind and between the buildings.[1] There is a heliport in the western corner of the city-state that is used for officials of the Holy See and official visitors.[3]
