Diamond Tower, known locally as Torre Diamante or the Diamantone, is a 140-metre faceted-glass office tower at Via Mike Bongiorno, 20124 Milano MI, in Milan’s Porta Nuova business district. Completed in 2012 during the redevelopment of the former Varesine rail-yard area, it draws architecture-minded visitors for its sharply angled silhouette, changing reflections and striking contrast with historic Milan.
What to Expect at Diamond Tower
This is a landmark to experience from the street rather than a public observation tower. The 26-storey building occupies the corner zone between Viale della Liberazione and Via Galileo Galilei, with its address on Via Mike Bongiorno. Its glass curtain wall is cut into irregular, sloping planes that evoke a cut gemstone; walk around the block to see how the profile shifts from a narrow blade to a broad, angular mass.
Diamond Tower is part of the wider Porta Nuova regeneration district, where contemporary towers, landscaped public space and pedestrian routes replaced former industrial and railway land. The offices are access-controlled, so there is no public lift, roof terrace, museum, café, guided tour, bag check or visitor restroom inside. Bring a camera, use the broad pavements and nearby park paths for exterior views, and respect security at the building entrances. Photography from public areas is the appropriate way to visit.
- Faceted façade: Slanted glass elevations and crisply folded edges create the diamond-like effect that gives the tower its name.
- 140-metre skyline marker: Completed in 2012, the tower is one of the defining high-rises of modern Milan.
- Porta Nuova setting: The building anchors the transition between the older Centro Direzionale office quarter and the newer Varesine development.
- Changing light: Morning and late-afternoon light brings out the blue-grey glass planes; overcast conditions emphasize the building’s angular geometry.
- Architecture walk: Pair exterior views with Piazza Gae Aulenti, the Bosco Verticale towers and Biblioteca degli Alberi Milan.

Visiting Tips, Getting There & Nearby Pairings
Come in the morning for cleaner lines and fewer people on the pavements, or near sunset when the façade catches warmer light from the west. There is no reservation system because there is no public interior visit. From Gioia station, exit toward Via Melchiorre Gioia and follow the pedestrian routes toward Via Mike Bongiorno; from Repubblica, walk north on Viale della Liberazione. Drivers should use a paid public garage in the district and avoid expecting access to the private office forecourt.
The surrounding streets and paths are generally paved and level, making an exterior circuit manageable for wheelchair users and strollers, though the office lobby and upper floors are not visitor facilities. Combine the stop with Piazza Gae Aulenti, about eight minutes away on foot, for its circular elevated plaza and fountains; Biblioteca degli Alberi Milan, roughly six minutes away, for lawns and designed planting; and Bosco Verticale, around 10 minutes away, for views of Stefano Boeri’s planted residential towers. The pedestrian links through Porta Nuova make this one of Milan’s easiest contemporary-architecture walks.
Frequently Asked Questions
When can I visit Diamond Tower, and what is the best time?
You can view and photograph Diamond Tower from surrounding public streets at any time. Go in early morning for quieter pavements or late afternoon for stronger reflections across its angled glass; office areas are not open for tourist visits.
Does Diamond Tower charge admission or require a reservation?
No. Exterior viewing is free and requires no ticket or reservation because Diamond Tower is an operating private office building, not an attraction with an observation deck. Do not plan on entering the lobby unless you have business there.
How much time should I allow for Diamond Tower?
Allow 20 to 40 minutes to circle the building, photograph the façade and take in the surrounding skyline. Budget up to two hours if linking it with Piazza Gae Aulenti, Biblioteca degli Alberi and Bosco Verticale.
Is Diamond Tower accessible for wheelchairs, children and strollers?
Yes for an exterior visit: the surrounding public pavements are largely level and wide enough for strollers and wheelchairs. There are no public galleries, lifts, toilets or family facilities inside the tower, so use the nearby public district amenities instead.
