Geography of Vatican City The geography of Vatican City is unique due to the country's position as an urban, landlocked enclave of Rome, Italy. With an area of 0.17 sqmi , it is the world's smallest independent state. Outside the Vatican City, thirteen buildings in Rome and Castel Gandolfo (the pope's summer residence) enjoy extraterritorial rights. (One building, the Paul VI Audience Hall, straddles the border, but its Italian portion has extraterritorial rights.) The country contains no major natural resources, and no known natural hazards other than those that affect Rome in general, such as earthquakes.
