Porta Soprana: when Barbarossa besieged Genoa and the city made itself strong

The twin towers of Porta Soprana tell the story of the challenge launched by Genoa against Frederick Barbarossa in the twelfth century, when the Republic chose independence and gave birth to Christopher Columbus.

In 1155, as Frederick Barbarossa descended from the Alps with the intention of bending the Lombard and Ligurian cities to his imperial will, the Genoese were completing one of the most imposing fortification works of their time. Porta Soprana, with its twin towers that still dominate the climb of the Colle, was not merely an entrance to the city: it was a stone manifesto, a way of telling the emperor that Genoa had no intention of submitting without a fight.

What we see today walking between via Dante and via di Porta Soprana is the result of a challenge launched eight centuries ago. A challenge that the Maritime Republic won, maintaining its independence and laying the foundations for that economic power that would dominate the Mediterranean for centuries to come.

But there’s more: just a few meters from that gate, according to tradition, a child was being born who would forever change the borders of the known world. Christopher Columbus, son of a weaver, growing up in the shadow of the walls that his father had seen being built.

The walls of Barbarossa: when Genoa chose freedom

The decision to build a new city wall was not by chance. In the 12th century, Genoa was undergoing a radical transformation: from a small village of fishermen and merchants it was becoming the naval power that would rival Venice and Pisa. Trade with the East, initiated during the Crusades, brought wealth but also enemies.

Frederick I Hohenstaufen, called Barbarossa, had clear plans for controlling northern Italy. For the emperor, the maritime cities were too independent, too rich, too proud. Genoa, in particular, had already shown it could navigate the waters of international politics with the same skill that its sailors used to navigate those of the Mediterranean.

The construction of the walls was an extraordinary operation for the time. The new circuit, over three kilometers long, enclosed an area six times larger than the previous fortification. Porta Soprana was the eastern pivot of this defensive system, built with stone blocks from Promontorio that still show their original solidity today.

The twin towers, approximately 20 meters high, were designed according to the most advanced principles of military engineering of the time. Genoese architects had studied Byzantine and Arab fortifications encountered during commercial travels, creating an original synthesis that combined defensive functionality and representative prestige.

Christopher Columbus: childhood in the shadow of the walls

Between 1451 and 1456, in a house just steps away from Porta Soprana, Christopher Columbus was born. The future discoverer of America grew up in a neighborhood that still retained its medieval character, where the tower houses of merchants alternated with the workshops of artisans and where the smell of the sea mingled with that of wool and fabrics.

Domenico Colombo, his father, was a weaver and innkeeper. The family did not belong to the merchant nobility that dominated the Republic, but was part of that artisan bourgeoisie that formed the backbone of the city’s economy. Christopher grew up hearing stories from navigators returning from the East, seeing ships laden with spices and silk docking in the port below.

The house where the future Admiral of the Ocean Sea probably was born was located in the area between the current Via del Mulino di Vento and Vico Dritto Ponticello, close to the walls. A position that allowed control of both the traffic entering the city and that heading towards the port.

Young Christopher had to pass through Porta Soprana every time he went outside the city, perhaps to accompany his father in his business dealings or to reach the sea. Those towers were part of his daily horizon, a symbol of a Genoa that looked at the world with ambition and courage.

The architecture of ambition: how they built in the twelfth century

Porta Soprana represents a masterpiece of medieval Ligurian military architecture. The two cylindrical towers, connected by a central body that housed the passageway, were designed to resist the sieges of the era but also to impress anyone approaching the city.

The builders used Promontory stone, extracted from quarries not far from the city. This stone, light gray in color with darker veining, had the advantage of being resistant but relatively easy to work with. The blocks were cut with millimeter precision, without the use of mortar for the most important parts of the structure.

The construction technique involved alternating layers of stones of different sizes, creating a pleasing aesthetic effect but above all guaranteeing maximum solidity. Inside the towers, stone spiral staircases allowed access to different levels, while loopholes were positioned strategically to ensure maximum field of fire.

The central passageway was protected by two successive gates and a system of sliding barriers that could completely isolate the entrance. Above the main arch, the coat of arms of the Republic reminded everyone that this was not merely a fortification, but the symbol of Genoese independence.

What remains: a journey through medieval Genoa

Today Porta Soprana is one of the best-preserved medieval monuments in Genoa, but it is not the only remnant of that grand defensive system. Walking along the course of the ancient walls means taking a journey through the city’s urban history, discovering how the urban landscape has accumulated layers over the centuries.

Starting from Porta Soprana, you can follow the line of the walls northward, along the current Via delle Mura della Malapaga. Here, amid 19th-century palaces and modern buildings, sections of the ancient fortification still emerge. Some are incorporated into more recent structures, others protrude like stone teeth from the contemporary urban landscape.

The ascent up Colle, which winds toward Castelletto, partially retraces the ancient wall line. From here you can appreciate the strategic logic of the fortification: to control the heights dominating the city, prevent potential enemies from setting up siege machinery there, and ensure an escape route inland in case of enemy landing from the sea.

Particularly striking is the section flanking the Luzzati Gardens, where medieval wall remains alternate with contemporary art installations. It’s a perfect example of how Genoa knows how to create a dialogue between past and present, keeping historical memory alive without turning it into a museum piece.

Columbus’s house, rebuilt in the 18th century on the remains of the original, now hosts a small museum that tells the story of daily life in 15th-century Genoa. In the immediate vicinity, the Sant’Andrea Cloister preserves the medieval atmosphere of the neighborhood, with its stone arches and central well.

The secrets of the stones: what history books don’t tell you

A curious detail that many overlook: the towers of Porta Soprana are not perfectly identical. Upon careful observation, one notices that the eastern tower is slightly taller and features different decorations. This is not due to a construction error, but to a precise strategy: the taller tower served as an observation point toward the eastern coast, from where Pisan threats could arrive.

Another interesting detail concerns its name. “Soprana” doesn’t mean “superior” in terms of quality, but rather “upper,” because the gate was located in the upper part of the city, as opposed to the “sottane” gates that opened toward the sea. It was a typically Genoese orientation system that reflected the particular topography of a city built between the sea and mountains.

During restoration work in the 1990s, graffiti and inscriptions left by medieval guards were discovered in the interior spaces of the towers. Some of these markings date back to the 14th century and tell stories of everyday life: names of soldiers, dates of service, small drawings that testify to how even then men felt the need to leave a trace of their passage.

Columbus’s Genoa today: living history

Walking today in the Porta Soprana neighborhood means immersing yourself in a Genoa that knows how to preserve its medieval soul without giving up contemporary vitality. The caruggi alleyways that branch off from the ancient gate teem with life: artisan shops that continue centuries-old traditions, small restaurants where you can taste Genoese cuisine, artists’ workshops that find inspiration in the city’s thousand-year history.

The area is perfect for those who want to experience Genoa from within, to feel part of that historical continuity that connects the medieval weaver to the modern visitor. Our residences in the historic center allow you to wake up each morning just steps away from Porta Soprana, to leave your home and find yourself immediately immersed in eight centuries of history.

It is an experience that goes beyond a simple tourist visit. It means walking on the same stones trodden by Christopher Columbus as a child, passing through the same gate that saw merchants departing towards Flanders, breathing the air of a city that has known how to reinvent itself without losing its identity.

Barbarossa’s walls no longer exist in their entirety, but their spirit survives. That desire for independence, that ability to look at the world with curious and enterprising eyes, that discreet pride that needs no ostentation: all of this is still here, in the stones of Porta Soprana and in the soul of those who choose to truly know Genoa.

If Genoa’s history fascinates you and you want to experience it as a protagonist, our residences await you in the heart of this city that has written unforgettable pages in the history of the world. Because the true Genoa is not visited: it is lived, it is breathed, it is carried in your heart as did its great sons who departed from this small Ligurian village to change the world.
