Porta Nuova Architecture: A Walking Guide to Milan's Skyline
Porta Nuova is the part of Milan where the city stopped looking backward. Between Garibaldi station, Corso Como and the Isola neighborhood, a former rail yard became a cluster of glass towers, raised squares and a park, and it now sets the skyline you see on every modern photo of Milan. This guide tells you who designed what, what to look for at street level, and how to walk it in an afternoon.
TL;DR
Porta Nuova is the contemporary district made of Garibaldi, Varesine and Isola. It is not the old Neoclassical gate of the same name.
Three master plans shaped it, by Pelli Clarke Pelli, Kohn Pedersen Fox and Boeri Studio, and the landmarks include the UniCredit Tower, Bosco Verticale and the Unipol Tower.
The best way to read it is on foot, from Piazza Gae Aulenti to the Biblioteca degli Alberi and on to Isola, in about two to three hours.
Go at golden hour: the glass is at its best, and the squares fill with Milanese after work.

Two Porta Nuovas: the gate and the district
The name causes confusion, so start there. The historic Porta Nuova is a Neoclassical arch with paired toll houses at Piazzale Principessa Clotilde, built in the Napoleonic period to replace an older Spanish-era gate. It is worth a look if you love 19th-century Milan, but it is not what people mean when they talk about skyscrapers.
The district is something else. YesMilano, the city’s official tourism portal, describes it as a large urban-renewal area begun in 2009, spreading around Porta Garibaldi, Isola and the former Porta Nuova and Varesine railway station. When people search for modern architecture in Milan, this is the place they are after.
How a rail yard became a skyline
The scale is the first thing to grasp. According to the ULI case study, the 290,000-square-meter development reconnects three neighborhoods that used to be cut off from one another, and it includes 170,000 square meters of public and pedestrian space. The project opened in 2012 after starting in 2006.
The money behind it was considerable too. An impact study on the regeneration reports that COIMA has co-developed and managed Porta Nuova since 2003, with a total investment of roughly €2.8 billion to rework an abandoned railway yard. At the peak of construction in 2012 it supported more than 2,200 jobs in the local construction supply chain, during a hard time for the Italian economy.
What makes it interesting to an architecture lover is that it was not drawn by one hand. The district has three master plans: Pelli Clarke Pelli Architects for Garibaldi, Kohn Pedersen Fox Associates for Varesine, and Boeri Studio for Isola. You can feel the three personalities as you walk: corporate and sculptural in Garibaldi, more orderly around Varesine, and looser and greener toward Isola.
The buildings that define the skyline
Here is a quick map of the landmarks, with the designers named in the district’s master-plan history.
Building | Architect | Where you notice it |
UniCredit Tower and the Gae Aulenti complex | Cesar Pelli | The curved ring of towers around the raised piazza |
Bosco Verticale | Stefano Boeri | The two planted residential towers near Isola |
Torre Diamante | Kohn Pedersen Fox | The faceted tower on the Varesine side |
Unipol Tower (Nido Verticale) | Mario Cucinella Architects | The curving, double-skin tower with the rooftop greenhouse |
Gioia 22 | Cesar Pelli | The slim tower along Via Gioia |
I Portali | Antonio Citterio Patricia Viel | The pair of towers by the Gae Aulenti side |
The attributions above come from the district’s development overview and the project pages quoted below.
UniCredit Tower and Piazza Gae Aulenti
The UniCredit Tower is the anchor of the skyline, and the piazza beneath it is the district’s living room. The square is raised above street level and fully pedestrian, so you walk up into it as if onto a stage. Look at how the curved towers frame the circular fountains and how the tower’s spire catches the last light. This is where you understand the idea of the district: buildings as backdrop, public space as the point.
Bosco Verticale
Stefano Boeri’s two residential towers are the image most travelers carry home. Italia.it notes the vegetation of roughly 1,000 trees and ties it to microclimate regulation and urban reforestation. Stand across the park and watch how the greenery changes with the season: lush in summer, rust and gold in autumn, thinner in winter. The facades are never the same twice, which is rare for a skyscraper.
The Unipol Tower
The Unipol Tower, nicknamed Nido Verticale, is 125 meters high and has a double-skin envelope and a panoramic rooftop greenhouse that hosts cultural events. Its softer, curving form is a useful counterpoint to the sharper glass towers beside it. Compare the two and you will see how different Milan’s answers to the “tall building” question can be.
I Portali
Designed by Antonio Citterio Patricia Viel, I Portali uses photovoltaic systems and high-performance facades, and is designed to comply with the NZEB standard. It is a quiet building next to loud neighbors, which is exactly why architecture students photograph it.
What makes it different from other modern Milan
Milan has plenty of modern architecture, from rationalist blocks of the 1930s to the CityLife towers. Porta Nuova stands apart for three reasons.
It was built as one connected place. LAND, the landscape designers involved, describe the guiding idea as permeability: fluidity between projects and the surrounding city, so the area becomes a destination and not just a passage. You feel this when you drift from a tower plaza into a garden without crossing a road.
The ground floor is public. Squares, bridges, cycle paths and parks run through the district. Italia.it lists Piazza Gae Aulenti, the Biblioteca degli Alberi, Bosco Verticale and Corso Como as the main public landmarks, with pedestrian and cycle routes and bridges linking them.
Sustainability is part of the design. The Portanuova Impact Report says the neighborhood was the first in the world to hold both LEED and WELL for Community certifications, runs without fossil fuels, and relies on geothermal heat pumps and solar panels. It also reports 90,000 square meters of green space, with biodiversity areas accounting for 25% of the district’s surface. The Biblioteca degli Alberi alone has about 500 trees and over 135,000 other plants.
The same impact study on the regeneration adds that extensive urban green areas can lower surface temperatures, which you can feel on a July afternoon when you step from an open plaza into the park.
A walking route through Porta Nuova
Plan on two to three hours at a relaxed pace. The route below runs south to north, so the skyline opens up first and the calm comes last.
Start at Garibaldi station. The district begins right outside, and the metro makes arriving easy.
Climb to Piazza Gae Aulenti. Walk the full circle of the raised piazza. Look up at the UniCredit Tower, then across at the curve of the surrounding buildings.
Cross toward Corso Como. The pedestrian street gives you the contrast between the old Milan of lower facades and the new towers behind it.
Walk into the Biblioteca degli Alberi. The park is built from botanical gardens, lawns and paths, with towers as the backdrop. This is the best place to sit and take in the skyline.
Continue to Bosco Verticale. View it from a distance first, then close up, to see how the planted balconies work.
Finish in Isola. Cross into the neighborhood for a different feel: smaller streets, local bars and the lively edge that existed before the towers.
The key habit is to look up, then down. The towers are one story; the paving, benches, bridges and planting are the other.
What to look for at each stop
Facades: notice reflective glass, double skins and planted terraces, and how each architect treats light.
Levels: the district uses raised platforms and bridges to separate people from traffic.
Edges: see where new meets old, such as the Garibaldi gate area and the Isola lanes.
Seasons: the planting is a living material, so what you see in October is not what you see in May.
Best time to go
Late afternoon is the sweet spot. Glass towers pick up a warm color near sunset, the squares fill with people, and the temperature drops in summer. Early morning is quieter and better for clean photographs of the facades without crowds. Weekdays show the business side of the district, while weekends show the leisure side.
Where to eat and rest nearby
A good architecture walk needs a pause. Around Piazza Gae Aulenti and Corso Como you will find cafes, restaurants and bakeries, while Isola has smaller, more local places. If you enjoy eating as a way of understanding a neighborhood, this urban food tourism guide shows how a city’s casual food scene can become part of your trip. Pick a spot with a view of the towers, then keep walking.
Our perspective: read the district as a story
We lead walks across Milan, and Porta Nuova is the neighborhood that most surprises people who think of the city as only cathedrals and fashion. Our view is simple: you do not need to know architecture jargon to enjoy it. You need to slow down and notice what a place wants you to do.
Here, the answer is that the district wants you to move. The raised squares pull you up, the bridges push you across, the park slows you down, and Isola releases you into everyday Milan. That sequence is the heartbeat of the place, and it is why we like to pair it with the rest of the city rather than treat it alone. Seeing a skyscraper beside a 19th-century gate and a neighborhood bar tells you more about Milan than any single building.
We also think the best way to see it is with a local host who can read the streets with you, tailor the pace to your interests and point out what a map will not. Our tours are private or small group, so you can stop where something catches your eye.

See Milan with a local host
If you would rather not navigate on your own, our Milan Highlights & Hidden Gems 2-hour walking tour starts from €35 and is led by a local host who builds the route around what you want to see. It is a good way to pair the modern skyline with the older, quieter corners of the city. For something more hands-on, our Paint & Sip workshop starts from €55, and both are on the same page.
