The first time I stood at the foot of the Bosco Verticale Milan towers, I did the thing every visitor does — I tipped my head back, squinted into the sun, and tried to count the trees clinging to the balconies. I gave up around 60. The actual number is closer to 800, plus 4,500 shrubs and 15,000 perennials wrapped around two residential towers in the Porta Nuova district. Stefano Boeri’s Bosco Verticale (literally “Vertical Forest”) opened in 2014 and changed how Milan thinks about its skyline, its sustainability arguments, and the way tourists move through the north of the city.
This guide is for the visitor who wants more than a glance and a selfie. I’ll cover where to photograph the Vertical Forest Milan from, what the architecture actually does, whether you can go inside (short answer: no, but there are ways around that), the wider Porta Nuova architecture loop, where to eat, and how to fit the whole thing into a half-day in 2026.

Why Bosco Verticale changed Milan’s skyline
Milan didn’t really have skyscrapers until very recently. For most of the 20th century the Pirelli Tower (1958) and the Torre Velasca were the tall buildings everyone pointed at, and the city’s profile stayed low and tile-roofed. Then the post-2008 Porta Nuova redevelopment happened, the UniCredit Tower went up in 2011, and suddenly Milan had a downtown cluster the size of a mid-tier American city. Bosco Verticale arrived right in the middle of that boom and gave the whole thing a thesis.
The thesis is simple, even if the engineering isn’t: cities are running out of horizontal ground for forests, so put the forests on the buildings. The 800 trees on these two towers are roughly the equivalent of two hectares of woodland packed into 1,500 m² of footprint. They absorb CO₂, filter particulates (Milan’s smog problem is real and chronic), buffer the apartments against summer heat, and house actual wildlife — there are bees, butterflies, and birds nesting up there now. Whatever you think of the aesthetics, the building works as a piece of infrastructure, and it has been copied in Nanjing, Utrecht, Lausanne, and a dozen other cities since.
For Milan specifically, the cultural shift mattered more than the carbon numbers. Before Bosco Verticale, Milan branded itself as a fashion-and-finance city. After it, Milan started winning architecture prizes (the towers took the International Highrise Award in 2014 and the CTBUH “Best Tall Building Worldwide” in 2015), and the city quietly repositioned itself as a design capital that also did green tech. The whole Porta Nuova district rides on that repositioning.
The architecture — Stefano Boeri, 800 trees, 4,500 shrubs, and what actually makes it work
The project is two towers — Torre E (also called Torre De Castillia, 111 m, 27 floors) and the shorter Torre D (76 m, 18 floors). Both are concrete-frame residential buildings with asymmetric cantilevered balconies stepping out at irregular intervals. The asymmetry isn’t decorative; it’s there so every tree has enough vertical clearance to grow, and so the heaviest tree clusters land directly over structural columns.
A few details that don’t usually make the guidebooks:
- The trees were chosen by botanists, not architects. Boeri’s office worked with horticulturalist Laura Gatti for two years selecting species — oaks, beeches, olives, cherries, apples — and pre-grew them in a nursery so they’d be wind-hardened before being craned onto the balconies.
- Each tree is anchored. Steel cables and root cages prevent any tree from blowing off in a Lombardy windstorm. After the towers opened, engineers tested the worst-case scenario by literally trying to pull a mature tree off a balcony with a winch. It didn’t move.
- The irrigation is centralized. A greywater system collects rainwater and apartment runoff, filters it, and delivers it via drip lines to every planter. Residents don’t water their own trees — a team of arborist-climbers (the press calls them “flying gardeners”) rappels down the facade twice a year to prune.
- The plants change with the seasons. This is the part no photo captures: visit in April and the towers explode in cherry blossom; in October they go copper and gold; in January the deciduous half goes bare and you can finally see the concrete bones underneath. Each season is a genuinely different building.
I think the strongest argument for the design is that it ages well. Most early-2010s skyscrapers already look dated — too much mirrored glass, too many parametric flourishes. Bosco Verticale gets better every year because the trees keep growing.
Where to photograph it from — 6 spots I actually use
The towers are surprisingly hard to photograph well. Get too close and you’re shooting straight up the wall and losing the silhouette; get too far and the trees disappear into a green blur. Here are the angles that work.
- Biblioteca degli Alberi (BAM park), south edge. Stand on the grass near the curving paths roughly 150 m southeast of the towers. You get both towers framed by the park’s own young trees, with a clean foreground. Best in late afternoon when the west sun hits the south facades.
- Piazza Gae Aulenti, upper ring. Walk up the gentle ramp on the east side of the elevated piazza and shoot back over the fountain pools. The fountains give you reflections, the UniCredit Tower anchors the right side of the frame, and Bosco Verticale sits center-left. This is the postcard shot.
- Via Gaetano de Castillia, street level. The east-facing side. Go at sunrise (around 6:30 a.m. in summer, 7:45 a.m. in winter) and the rising sun lights the foliage from behind for a backlit, glowing effect. Almost no one is here at that hour.
- UniCredit Pavilion + Corso Como bridge. The pedestrian footbridge between Corso Como and Piazza Gae Aulenti gives you a slightly elevated angle and lets you compose both towers against the UniCredit Tower’s spire. Good blue-hour location.
- Via Confalonieri / Isola side. Walk into Isola via the underpass and look back south. You get the trees in profile against the Porta Nuova skyline behind, and the older Isola buildings in the foreground for scale contrast. Underrated.
- ADI Design Museum rooftop terrace. Free access to the museum’s upper-level outdoor space, looking east toward the towers. Best at golden hour.
Full disclosure — I have a longer breakdown of Milan photography spots if you want angles for the rest of the city too.

The Porta Nuova / Isola architecture loop — what else to see
Don’t just photograph Bosco Verticale and leave. The whole Porta Nuova / Isola pocket is one of the densest concentrations of contemporary architecture in Europe, and you can walk the entire loop in 90 minutes. Here’s the route I do with first-time visitors:
- UniCredit Tower — César Pelli, 2011. At 231 m it’s still Italy’s tallest building. The spire alone is 78 m. Walk underneath it and look straight up.
- Piazza Gae Aulenti — the elevated circular plaza named for the architect of Musée d’Orsay’s interior. Fountains, three reflecting pools, and the strongest free Wi-Fi in north Milan if you need it.
- Diamond Tower (Diamantone) — Kohn Pedersen Fox. The faceted facade that catches the light differently every hour. Often missed because Bosco Verticale sucks all the attention.
- Solaria, Solea, and Aria — the three Arquitectonica residential towers between BAM and the railway. Solaria at 143 m was the tallest residential building in Italy when it opened in 2013.
- Bosco Verticale — the main event. Slow down here.
- ADI Design Museum — opened 2021 in a converted tram depot on Piazza Compasso d’Oro. Houses the Compasso d’Oro design awards collection. Worth an hour even if you’re not a design nerd.
- Casa della Memoria — Baukuh, 2015. A small brick monument to 20th-century Italian resistance, decorated with a tiled photo-mosaic facade. Quietly one of my favorite buildings in Milan.
- Fondazione Feltrinelli — Herzog & de Meuron’s elongated glass-and-zinc complex on Viale Pasubio, a 10-minute walk west. Looks like a giant tilted greenhouse.
If you’re a member of the architecture-pilgrim demographic, there’s a longer list in my full Milan attractions guide.
Can you go inside? Residence access, restaurants, and the workarounds
The honest answer is no — the apartments are private residences, the lobbies are key-card only, and there is no public observation deck inside either Bosco Verticale tower. Buildings have sold for €1.5–3 million per apartment in recent years and the residents are protective of their privacy. So if a tour operator promises you “inside access,” they mean a guided walk around the base.
That said, there are three legitimate ways to get closer than street level:
- The base-level retail spaces. The ground floor of Torre E houses a few commercial tenants that rotate. As of 2026 you can step into the lobby area of the co-working space and a small art gallery without challenge. You won’t see balconies, but you’ll feel the building.
- Stefano Boeri Architetti open days. Boeri’s own studio occasionally runs guided architecture days during Milan Design Week (April) and the Open House Milano weekend (usually late May). These sometimes include rooftop access. Watch the Open House Milano website in February for the program.
- Book a stay in the neighboring Bosco Suite Milan or the Hyatt Centric at Piazza Gae Aulenti — both have upper-floor rooms with direct facade views. Not inside, but eye-level with the trees.
There are no restaurants inside Bosco Verticale itself. The closest dining at the base is in the connected Porta Nuova retail strip, covered below.
Where to eat around Porta Nuova — 5 spots I actually return to
- Ratanà (Via Gaetano de Castillia 28, Isola) — the Michelin-starred Milanese kitchen that anchored the neighborhood before it gentrified. Chef Cesare Battisti’s risotto alla milanese con ossobuco is the version against which I judge all others. Around €70–90 per person for the tasting menu, €40 à la carte at lunch.
- Berberè Isola (Via Sebenico 21) — wood-fired Neapolitan-style pizza on naturally leavened sourdough. The Margherita is €11; the Cosacca with pecorino and tomato is the one I order. Walk-in only at lunch, book for dinner.
- Frida (Via Antonio Pollaiuolo 3, Isola) — courtyard bar and restaurant that’s been a neighborhood institution since 2002. Aperitivo board with a Negroni for around €12. The garden is shaded and there’s live music on Thursdays.
- Pavé Gelati & Granite (Via Cesare Battisti or the Porta Nuova branch) — best gelato within walking distance. The pistacchio di Bronte is uncut with sugar and tastes like roasted nuts. €4 for two scoops.
- Dry Milano (Via Solferino 33, a 12-minute walk south into Brera) — cocktails and pizza in the same room, designed by Vudafieri-Saverino. Pizza €10–15, cocktails €13. Worth the walk if you want one more design hit before you call it a night.

Practical tips — light, drones, crowds
- Best light: golden hour, roughly 45 minutes before sunset. The west-facing facade glows; the foliage takes on a warm rim. In summer that’s around 8:30 p.m.; in winter around 4:15 p.m.
- Blue hour (the 20 minutes after sunset) is the other great window. Lights come on inside the apartments and the building reads as a luminous green column against a deep blue sky.
- Drone rules: recreational drone flight over central Milan is heavily restricted. The whole Porta Nuova area sits inside a controlled airspace zone, and you need ENAC authorization plus a flight permit from the Milan municipality. Realistically, do not bring a drone unless you’ve filed paperwork weeks in advance. Police do enforce this.
- Tripods: fine on public sidewalks and in BAM park. Not allowed in Piazza Gae Aulenti’s upper ring without a permit — security will ask you to pack it up.
- Bathrooms and water: public toilets in the Coima offices at Piazza Gae Aulenti (free, behind the reception desk), and water fountains throughout BAM park.
- Getting there: M2 (green) and M5 (lilac) lines both stop at Garibaldi FS, three minutes’ walk south. From the Duomo it’s a single M3 to Repubblica then a 7-minute walk, or 18 minutes on foot through the gallery streets.
Best time to visit — season, time of day, weekends vs weekdays
I have opinions here.
Season: April and October are the best months. April catches the cherry-blossom phase and a cool Milan that hasn’t gone humid yet; October gives you the autumn-color version of the building, which is genuinely spectacular and almost never photographed. Avoid August — locals are away, restaurants close for two weeks, and the heat in Porta Nuova (concrete, glass, no shade) is brutal.
Time of day: sunrise for solitude, golden hour for photos, blue hour for the lit-up version. Midday is the worst — harsh light flattens the foliage and the plaza fills with tour groups.
Weekday vs weekend: weekdays are dramatically calmer. Saturday afternoons the Piazza Gae Aulenti area gets packed with Milanese families and shoppers from the connected Corso Como retail strip; weekday mornings you can have the place almost to yourself. If you’re constrained to weekends, go Sunday morning — it’s the quietest window.

The bigger architecture story — Milan since Expo 2015
Bosco Verticale didn’t happen in a vacuum. Milan staged Expo 2015 (“Feeding the Planet”), and the run-up to that event triggered the biggest construction wave the city had seen since the postwar period. Three projects worth your time if you’ve already done Porta Nuova:
- CityLife — on the west side, a 20-minute metro ride. Three towers by Zaha Hadid (the twisting “Lo Storto”), Arata Isozaki (the rectilinear “Il Dritto”), and Daniel Libeskind (the leaning “Il Curvo”). Surrounded by a residential complex also designed by Hadid and Libeskind, plus a large car-free park. The shopping mall underneath has the best architecture-coffee combo in Milan.
- Fondazione Prada — Rem Koolhaas / OMA, opened 2015 on a converted gin distillery site in southern Milan. The gold-leafed “Haunted House” is the obvious image but the whole compound rewards an hour of slow walking. €15 entry, often runs major contemporary art shows.
- Fondazione Feltrinelli — Herzog & de Meuron’s elongated complex in Porta Volta, mentioned above. Free to wander the ground floor.
Together with the Duomo (Gothic, six centuries in the making — see my Milan Duomo guide), the Castello Sforzesco (15th-century Sforza fortress), and La Scala (1778), these contemporary projects give Milan a 600-year architectural sweep that very few European cities match.
Combine with nearby — Isola, Brera, Garibaldi
Three neighborhoods sit within a 15-minute walk of Bosco Verticale, and each gives you a different mood.
Isola (literally “island,” because the railway used to cut it off from the rest of Milan) is directly north. Once working-class, now a creative-class enclave full of vintage shops, jazz bars, and tattoo studios. The Stecca 3.0 community building and the Frida courtyard are the unofficial centers. My full Isola Milan guide covers the bar crawl in detail.
Brera is the cobblestoned 18th-century neighborhood 15 minutes south on foot. Pinacoteca di Brera (the Caravaggios, the Mantegnas), the Brera Botanical Garden, and dozens of small galleries. Total tonal contrast with Porta Nuova — go from gleaming glass towers to wisteria-draped courtyards in under a kilometer.
Garibaldi is the train-station gateway to the south of Porta Nuova, with Corso Como (Milan’s nightlife spine) leading into it. The 10 Corso Como concept store designed by Kris Ruhs is worth a browse even if you don’t buy anything.

FAQ
Can you go inside Bosco Verticale?
No. Both towers are private residences with no public observation deck or tour of the apartments. You can photograph and walk all around the base, and occasionally Open House Milano (May) or Milan Design Week (April) runs limited access events. Otherwise, admire from outside.
How much does it cost to visit?
Free. There’s no ticket. The surrounding BAM park, Piazza Gae Aulenti, and all the surrounding streets are public space. Guided architecture walks of the Porta Nuova district cost €25–40 per person if you want one.
How long do I need at Bosco Verticale?
30 minutes for the towers alone, 90 minutes if you walk the full Porta Nuova architecture loop, half a day if you also do Isola and lunch. I’d budget at least two hours.
Is Bosco Verticale worth visiting?
If you have any interest in architecture, sustainability, or contemporary design — yes, absolutely. If your trip is strictly historical (Duomo, Last Supper, Sforza castle), it’s still worth 30 minutes because it tells you what Milan is becoming, not just what it was.
When is the best time of year to see Bosco Verticale?
Late April for cherry blossom and full spring foliage, or mid-October for autumn color. Both seasons photograph dramatically and the Milan weather is mild.
How do I get to Bosco Verticale from the Duomo?
Take metro M3 (yellow) one stop north to Repubblica, then walk 7 minutes northwest. Total time around 15 minutes. Or walk the whole way in roughly 25 minutes via Via Manzoni and Brera, which is the more scenic option.
Final thoughts
Of all the buildings I drag visiting friends to in Milan, Bosco Verticale is the one that gets the most surprised reactions. People expect a clever architectural gimmick and find a genuinely functional piece of city — the trees are real, the apartments are lived in, the bees and birds are actual residents. The fact that it works as both a design statement and a working ecosystem is what keeps it interesting six visits in.
Pair it with an hour in Isola, lunch at Ratanà, and a slow walk back through Brera, and you’ve got one of the most varied half-days Milan offers.
