Inside the World's Smallest State: A Guide to Vatican City's Hidden Cities

Inside the World's Smallest State: A Guide to Vatican City's Hidden Cities

Vatican City occupies a unique place in the human imagination: instantly recognizable, yet rarely understood beyond its postcard facades. Evelyn Murphy's Cities of Vatican City dismantles the tourist's view by treating the enclave as what it actually is—a fully functioning sovereign state where spiritual authority, artistic heritage, and municipal administration share the same cobblestones. The book's central insight is that Vatican City contains not one city but many, each defined by its own history, workforce, and purpose.

What the Book Is About

Murphy structures the book as a guided tour through 25 chapters, each dedicated to a distinct "city" within the city-state. The opening chapters trace the territory's evolution from the marshy Vatican Hill of antiquity through the Constantine basilica, the Papal States era, the "Roman Question" standoff, and the 1929 Lateran Treaty that birthed the modern state. Subsequent sections move systematically through St. Peter's Basilica and Square, the Sistine Chapel, the Vatican Museums, the Apostolic Palace, and the Vatican Gardens before pivoting to the administrative machinery: the Palace of the Governorate, the Paul VI Audience Hall, the Vatican Library, the Observatory, the Swiss Guard barracks, the post office, the railway station, and the heliport. Later chapters examine the economy (coins, stamps, tourism), governance structure, citizenship rules, artisan workshops, sustainability initiatives, and visitor logistics. The intended reader is someone who wants more than a travel guide—someone curious about how a nation of 800 residents and zero birthright citizens actually operates day to day.

The Vatican Hill as Palimpsest

Chapter Two reveals that the ground beneath St. Peter's Square has served as an Etruscan oracle site, Agrippina's imperial gardens, Caligula's circus, a pagan necropolis, and a Christian martyrdom ground—all before Constantine built the first basilica. Murphy writes that the hill's name may derive from vaticinium, Latin for "prophecy," due to an ancient Etruscan oracle believed to have been located there. The chapter traces how each layer of use—imperial spectacle, burial ground, pilgrimage destination, papal residence—left physical traces that subsequent builders either incorporated or deliberately erased. The Leonine Walls of the ninth century, erected after the Saracen sack of 846, created the first fortified boundary that would eventually become the state's border. This archaeological depth explains why the Vatican feels less like a planned capital and more like a geological formation compressed by centuries of intentional reuse.

Administration Without a Civil Service Tradition

One of the book's most surprising sections details how Vatican City runs a modern bureaucracy without a traditional civil service. Chapter Eleven introduces the Palace of the Governorate, built only in 1927—two years before the state existed—and describes its departments managing everything from urban planning to the fire brigade. Chapter Twenty explains that legislative power rests with a Pontifical Commission of seven cardinals appointed by the Pope, while executive authority is delegated to the President of the Governorate. A 2023 legal amendment now allows a non-cardinal, including a woman, to hold that post; Sister Raffaella Petrini's appointment is noted as a historic shift. Chapter Twenty-One adds that citizenship is granted only by appointment to serve the Holy See and revoked when the appointment ends—there are no native-born citizens, no hospitals, and no schools. The result is a state whose entire population is, by definition, its workforce.

Infrastructure at Micro-Scale

Chapters Sixteen through Eighteen catalog the practical systems that keep the enclave running. The Vatican Post Office, established days after the Lateran Treaty, processes 140 tonnes of mail and six million postcards annually and has been called "one of the best postal systems in the world" by the Universal Postal Union. The Città Vaticano railway—300 meters of track, a single station, and the title of world's shortest national railway—primarily hauls freight but has carried popes on ceremonial journeys since 1962. The heliport, tucked into the Vatican Gardens since 1976, shuttles the Pope to Castel Gandolfo in minutes rather than hours. Each system is sovereign in name but operationally intertwined with Italy: trains and locomotives come from Ferrovie dello Stato, air traffic control is Italian, and water supply is subsidized by Rome. Murphy presents these not as quirks but as deliberate choices that preserve independence while acknowledging geographic reality.

Artisans as Living Infrastructure

Chapter Twenty-Two argues that the Vatican's masterpieces survive because the state maintains the craftspeople who made them. The Vatican Mosaic Studio, founded in the late sixteenth century, still employs artisans who select from over 27,000 shades of glass enamel to replace frescoes that would not survive the basilica's humidity. The chapter notes that a single large mosaic can take decades, requiring "the collaborative effort of numerous skilled artisans." Beyond mosaics, the book describes restoration labs for paintings, sculptures, textiles, and manuscripts; book conservators in the Vatican Library; woodcarvers, gilders, and stonemasons for the palaces; and embroiderers and goldsmiths for liturgical vestments and vessels. These workshops are not tourist attractions—they are operational necessities. Murphy frames them as a "hidden, yet vital, 'city' of skill" that makes preservation a continuous act rather than a one-time project.

Sustainability as Theological Practice

Chapter Twenty-Three reframes environmental initiatives as expressions of Catholic social teaching rather than modern add-ons. The 2,400 solar panels on the Paul VI Audience Hall roof, installed in 2008, power the entire hall. Historic fountains have been retrofitted with closed-loop water recycling. Rainwater harvesting irrigates the Vatican Gardens, which cover half the territory and function as the city's "lungs." The chapter cites Pope Francis's encyclical Laudato Si' and the concept of "integral ecology" as the doctrinal basis for these choices. Even the vehicle fleet is shifting toward electric models. Murphy suggests that for Vatican City, sustainability is not a policy goal but a form of doctrinal consistency—caring for creation as an extension of the spiritual mission.

Who Should Read This

Readers who enjoy urban history, institutional biography, or the logistics of unusual states will find this book rewarding. It works equally well as a pre-trip deep dive for Vatican visitors who want to understand what they're looking at, and as a standalone study of how sovereignty operates at the smallest possible scale. People looking for a devotional text or a purely art-historical survey should look elsewhere—Murphy's focus is structural and operational, not devotional. The prose is clear and accessible, but the density of detail rewards patience; this is a book to read in sections, not a single sitting.
