Geography and Environment of Holy See
Terrain, climate, natural resources, hazards, and environmental conditions of Holy See.
Overview
The state of Vatican City is the smallest sovereign state in the world. A tiny enclave within the city of Rome, it occupies 109 acres and is almost completely surrounded by medieval walls. As a result of the Lateran Pacts of 1929, the Italian Government granted St. Peter’s Basilica and Square and the surrounding area within the Vatican walls as the Holy See’s sovereign and independent territorial base. Besides St. Peter’s, Vatican City also includes the Apostolic Palace, administrative and residential buildings, museums, archives, and libraries, a cemetery, and gardens covering almost one-third of the entire area. Thirteen other buildings in Rome, as well as the Pope’s summer residence at nearby Castel Gandolfo, enjoy extraterritoriality under the terms of the Lateran Pacts.

Natural Resources and Hazards
- Natural Resources
- As the world's smallest internationally recognized independent state, the Holy See possesses virtually no conventional natural resources in the traditional sense. Encompassing only approximately 0.44 square kilometers within the city of Rome, Italy, the Vatican City territory offers no agricultural land, no mineral deposits, no forests, and no significant bodies of water that could be exploited for resource extraction or energy production. The land itself is almost entirely urbanized, covered by the magnificent structures of Vatican City, including St. Peter's Basilica, the Apostolic Palace, the Vatican Museums, and the Sistine Chapel. There are small, meticulously maintained gardens covering roughly half the territory, but these serve ornamental and recreational purposes rather than food production or commercial agriculture. Given this extreme physical limitation, the Holy See relies entirely on imported energy, food, and raw materials. Electricity is supplied through an interconnection agreement with Italy's national grid, and the territory has no indigenous fossil fuel reserves or hydroelectric capacity. In recent years, the Vatican has made notable strides toward renewable energy adoption, installing solar panels on the roof of the Paul VI Audience Hall and exploring further sustainability initiatives in alignment with the Holy See's broader environmental teachings, particularly those expressed in the papal encyclical Laudato Si'. What the Holy See does possess in abundance are extraordinary non-material resources of immense global significance. Its vast art collections, architectural heritage, and archival holdings represent an unparalleled concentration of cultural and historical wealth accumulated over nearly two millennia. The Vatican Apostolic Archive alone contains documents spanning over twelve centuries of history, and the Vatican Museums hold one of the world's most visited collections of art and antiquities. These cultural assets, though not natural resources in an economic or geological sense, form the cornerstone of the state's identity and its enduring global influence.
