Firenze Capitale transformed Florence more dramatically than almost any other period in the city’s modern history. When Florence became capital of the Kingdom of Italy in 1865, a city still shaped by medieval walls and Renaissance streets suddenly had to accommodate a royal court, parliament, ministries, diplomats and thousands of new residents.
The changes went far beyond individual buildings. Large sections of the old fortifications disappeared, broad avenues replaced defensive walls, new neighbourhoods expanded beyond the historic centre and Giuseppe Poggi transformed the hills south of the Arno into an ambitious urban landscape. Florence remained Italy’s capital for only six years, but much of the modern city still reflects decisions made during this period.
Period: 1865–1871
Key urban planner: Giuseppe Poggi
Major change: Demolition of large sections of the medieval walls
New infrastructure: Viali di Circonvallazione
Urban expansion: New residential districts beyond the former walls
Southern transformation: Viale dei Colli, Le Rampe and Piazzale Michelangelo
Royal residence: Palazzo Pitti
Long-term importance: Florence changed from a compact walled city into a modern European urban centre
This article focuses on the physical transformation of the city. For the wider political story, see our Florence as Capital of Italy – Firenze Capitale 1865–1871.
Florence Before Firenze Capitale
In the early 1860s, Florence looked very different from the city we know today. Much of the historic centre was still enclosed by the last major circuit of medieval walls, and gates controlled the principal routes into the city.
Inside the fortifications, dense networks of narrow streets reflected centuries of gradual development. Beyond the walls, the landscape quickly became more rural, with villas, gardens, fields and small settlements occupying areas that would later become part of the expanding city.
This urban structure had served Florence as the former capital of the Grand Duchy of Tuscany. It was far less suited to the demands of a modern national administration.
The Duomo, Palazzo Vecchio and Renaissance palaces were already familiar landmarks, but Florence was still physically defined by medieval walls and gates. Within only a few years, much of that centuries-old boundary would disappear.
A Capital Needed Space
The decision to transfer the Italian capital from Turin to Florence created immediate pressure on the city.
Government ministries required offices, while members of parliament, civil servants and diplomats needed accommodation. The royal household brought further demand for housing, services and ceremonial spaces.
Hotels, restaurants, shops and transport also had to respond to a sudden increase in population and political importance.
The challenge was therefore not simply where to place parliament or individual ministries. Florence had to reconsider how the entire city functioned.
Giuseppe Poggi and the New Florence
The central figure in the physical transformation was Florentine architect and engineer Giuseppe Poggi.
As the transfer of the capital approached, Poggi was commissioned to prepare an ambitious plan for the enlargement of Florence. His proposals addressed the immediate needs of the new capital while also anticipating future urban growth.
Poggi did not attempt to replace historic Florence with an entirely new city. Instead, he created a framework connecting the old centre with expanding districts beyond it.
His plan included new avenues, residential quarters, squares, infrastructure and major changes to the medieval fortifications. South of the Arno, he developed an entirely different approach based on panoramic roads and landscaped hillsides.
Poggi’s plan belonged to a wider nineteenth-century European movement in urban planning. Paris, Vienna and other major cities were also creating broad boulevards, improving circulation and expanding beyond obsolete defensive structures.
The Medieval Walls Become an Obstacle
Florence’s walls had protected and defined the city for centuries. By the mid-nineteenth century, however, planners increasingly regarded them as obstacles to expansion and traffic.
The fortifications restricted movement between the historic centre and growing areas beyond them. They also occupied valuable land along the edge of the city.
Poggi’s plan therefore proposed removing large sections of the walls, particularly north of the Arno.
The decision was radical. Florence lost a major part of its medieval defensive structure, permanently changing both the appearance and the boundaries of the city.
For the broader history of the fortifications, see our Florence City Walls and Fortresses – Complete Guide.
The Creation of the Viali di Circonvallazione
The demolition of the walls created space for one of the most recognisable features of modern Florence: the Viali di Circonvallazione.
These broad, tree-lined avenues followed much of the former line of the fortifications north of the Arno. They created a new circulation system around the historic centre and connected neighbourhoods developing beyond the old city.
For centuries, the walls had represented a clear boundary between Florence and the surrounding landscape. Poggi transformed that boundary into a zone of movement and expansion.
Today, the Viali still provide one of the clearest indications of where historic Florence ends and the predominantly nineteenth- and twentieth-century city begins.
The transformation is explored in more detail in Florence City Walls and the Viali di Circonvallazione.
Walk from the historic centre towards Piazza Beccaria or Piazza della Libertà. The sudden transition from narrow streets to broad avenues marks approximately the former line of Florence’s medieval fortifications.
Old City Gates Become Urban Monuments
The surviving gates provide some of the clearest evidence of how Firenze Capitale transformed Florence.
Porta alla Croce now stands in Piazza Beccaria, while Porta San Gallo survives at Piazza della Libertà. Porta al Prato occupies another busy modern junction.
Without the surrounding walls, their original defensive function can be difficult to imagine. Poggi incorporated these historic structures into the new urban plan, and large squares developed around them.
Former entrances through a continuous defensive system therefore became isolated monuments within the expanding modern city.
Our guide to the Historic Gates of Florence – From Porta Romana to San Niccolò explains how these structures once functioned.
The medieval gateways remained approximately where they had always stood. What disappeared were the walls that once connected them.
New Neighbourhoods Beyond the Walls
Removing the fortifications released Florence from physical limits that had constrained its growth for centuries.
New streets and residential districts appeared beyond the former walls, while areas previously considered peripheral became increasingly integrated into the city.
The expansion reflected both practical necessity and changing expectations about urban life. Newer districts could provide broader streets, larger residences, gardens and more open surroundings.
The arrival of government officials, professionals and wealthier residents created strong demand for this type of housing.
Florence consequently developed a clearer distinction between the dense historic centre and the more spacious neighbourhoods of the modern city.
Piazza d’Azeglio and the New Residential Florence
Piazza d’Azeglio provides one of the best examples of the new residential Florence.
The elegant square and surrounding streets developed east of the historic centre as part of the nineteenth-century expansion beyond the old walls.
Large residences, greenery and a more regular street pattern offered a very different environment from the medieval neighbourhoods nearby.
The area demonstrates that Firenze Capitale transformed not only monumental roads and public spaces but also the way wealthier Florentines and newcomers lived within the city.
Campo di Marte and the Expanding City
Areas east and northeast of the former walls also became increasingly important as Florence expanded.
The wider Campo di Marte area would be transformed much more extensively during the twentieth century, but its integration belongs to the longer process through which Florence expanded beyond its traditional boundaries.
The capital years accelerated this outward movement. Once the fortifications no longer defined the city, development could follow new roads and transport routes into previously peripheral areas.
A New Relationship with Transport
Modernising Florence also required better connections with the rest of Italy.
Railways had reached the city before Firenze Capitale, but the arrival of the national government dramatically increased their importance. Politicians, officials, diplomats and visitors needed reliable connections with Turin, Bologna, Rome and other Italian cities.
Goods and correspondence also moved in greater quantities.
Within Florence, Poggi’s avenues created a new system of circulation. The city was beginning to move away from a transport structure shaped primarily by medieval streets towards one designed for much larger flows of people and vehicles.
Changes South of the Arno
Poggi treated the landscape south of the Arno differently from the relatively flat areas north of the river.
Significant sections of the historic walls survived here, and the steep hills made another ring of broad avenues impractical.
Instead, Poggi used the landscape itself to create one of his most imaginative projects.
The Viale dei Colli curved through the hills above Florence, linking roads, villas and new residential areas while providing carefully staged views across the city.
Urban planning became not only infrastructure but an aesthetic experience.
North of the Arno, Poggi replaced much of the old defensive perimeter with broad avenues. South of the river, he worked with the hills to create panoramic roads and landscaped viewpoints.
Piazzale Michelangelo and a New Way of Seeing Florence
The most celebrated element of Poggi’s hillside vision became Piazzale Michelangelo.
The terrace was completed as part of the wider programme initiated during Firenze Capitale, although elements of the project continued after Florence ceased to be the national capital.
From this elevated position, Florence could be seen almost as a single work of art: the Duomo, Palazzo Vecchio, Santa Croce, the Arno and the surrounding hills forming one panoramic composition.
This represented more than the creation of an attractive viewpoint. The historic city itself had become something to be deliberately observed from the modern city developing around it.
The famous panorama from Piazzale Michelangelo is itself part of Florence’s nineteenth-century transformation. Poggi deliberately created a viewpoint from which the historic city could be admired as a complete landscape.
Le Rampe and the Designed Landscape
Below Piazzale Michelangelo, Poggi created another remarkable urban landscape.
The system known as Le Rampe connects the hillside above San Niccolò through terraces, stairways, vegetation, grottoes and water features.
These structures also served practical purposes by helping manage the steep terrain and water.
Yet Poggi designed them as part of the visual experience of moving between the lower city and the panoramic heights above Florence.
Nearby Porta San Niccolò creates an extraordinary contrast between Florence’s medieval defensive history and its nineteenth-century transformation.
Palazzo Pitti Becomes a Royal Palace
The changes during Firenze Capitale were not limited to streets and neighbourhoods.
Palazzo Pitti became the principal Florentine residence of King Victor Emmanuel II.
The former Medici and grand-ducal palace now served the monarchy of the newly unified Kingdom of Italy.
Other historic buildings were adapted for government departments and public institutions. The capital therefore changed the function of existing Florence as well as its physical form.
Palazzo Pitti tells more than the story of the Medici. During Firenze Capitale, it also became one of the principal political residences of unified Italy.
Thousands of New Residents Change Daily Life
The arrival of the national government brought thousands of people connected with political and administrative life.
Civil servants, politicians, military personnel, diplomats, journalists and members of the royal household joined the existing population. Their families and supporting professions created further demand.
Housing prices rose, while restaurants, cafés, hotels and shops benefited from new customers.
Florence also became a meeting place for people arriving from regions that had only recently belonged to separate political states.
In this sense, Firenze Capitale changed not only architecture but also the social rhythms of the city.
The Cost of Becoming a Capital
Modernisation came at a considerable price.
Major infrastructure projects required substantial investment, while land speculation and rapid construction added further economic complexity.
Expectations that Florence would continue growing as a national political centre influenced property development and municipal expenditure.
When the capital moved to Rome in 1871, Florence therefore faced a difficult adjustment.
Government offices departed, the royal court moved away and many residents whose livelihoods depended on the national administration left the city. The investments, however, remained.
Florence Loses the Capital but Keeps the New City
The capture of Rome by Italian forces in 1870 fundamentally changed the political situation.
Rome became part of the Kingdom of Italy, removing the main obstacle that had prevented it from serving as the national capital. In 1871, the government moved from Florence to Rome.
There was no way to reverse the transformation Florence had already undergone.
Demolished walls could not be rebuilt, while new avenues, streets and districts had permanently altered the city’s structure.
Projects associated with Poggi’s plan also continued after 1871. Florence had lost its political role but inherited the modern city created for it.
The Transformation Continued After 1871
One important distinction is often overlooked: not every major nineteenth-century transformation of Florence occurred between 1865 and 1871.
Several projects associated with Poggi continued after the capital moved to Rome. Even more significantly, the radical redevelopment of the Mercato Vecchio district in the historic centre occurred mainly during the 1880s and 1890s.
These later interventions belonged to a continuing culture of modernisation rather than directly to the six years when Florence served as capital.
Nevertheless, Firenze Capitale had greatly accelerated the idea that Florence could and should be redesigned to meet modern requirements.
Firenze Capitale and the later Risanamento are closely related but not identical. The capital years began the great modernisation of Florence, while some of the most controversial demolitions in the historic centre occurred decades later.
What Firenze Capitale Did Not Change
Despite the scale of the transformation, Florence did not become an entirely different city.
The core of medieval and Renaissance Florence survived. The Duomo, Palazzo Vecchio, Santa Croce, Santa Maria Novella and countless palaces and streets remained at the centre of urban life.
Poggi’s plan primarily transformed the relationship between this historic core and the expanding city around it.
That distinction remains fundamental today: the historic centre is extraordinarily dense and monumental, while a new system of boulevards and neighbourhoods developed around it.
How to See the Transformation Today
The legacy of Firenze Capitale can still be explored easily on foot.
Begin near Piazza della Libertà, where Porta San Gallo recalls the medieval wall circuit. Follow the Viali di Circonvallazione towards Piazza Beccaria and notice how dramatically the scale changes compared with streets inside the historic centre.
At Piazza Beccaria, Porta alla Croce provides another striking example of a medieval gate transformed into an isolated urban monument.
Then cross the Arno towards San Niccolò. From here, Le Rampe lead upwards through Poggi’s designed landscape towards Piazzale Michelangelo.
The route reveals both sides of his plan: practical modernisation and the creation of a new scenic relationship between Florence and its surrounding hills.
Walk from the narrow streets around Santa Croce to Piazza Beccaria and continue along the Viali. Within a short distance, you move from the urban scale of medieval Florence into the city created by nineteenth-century expansion.
Why the Transformation of Firenze Capitale Still Matters
How Firenze Capitale transformed Florence still matters because the modern city cannot be understood through Renaissance history alone.
The six capital years accelerated changes that might otherwise have taken decades. Florence opened beyond its medieval boundaries, new avenues altered circulation, residential districts expanded outward and the hills became part of an ambitious urban plan.
The transformation also forced Florence to confront a question that remains relevant today: how can a city of extraordinary historical importance adapt to modern life without losing the character that makes it unique?
The nineteenth-century answers would not always be accepted today. Demolishing large sections of the medieval walls represented an enormous loss of historic fabric, while later redevelopment in the centre became even more controversial.
Yet the results are inseparable from Florence as we know it. Broad avenues outside the dense historic core, medieval gates standing alone in large squares and panoramic roads winding through the hills all lead back to the transformation initiated during Firenze Capitale.
The Renaissance shaped the monuments of Florence. Firenze Capitale reshaped the city around them.
