The Vertical Forest

The Vertical Forest

A walk through Porta Nuova, the district Milan built upward on abandoned railway land, where towers wear real trees and a botanical park answers them at ground level. It ends on the surprise that this leap forward is a sequel to something the city did decades ago.

Piazza Gae Aulenti: The Raised Heart

A circular public square lifted about six metres above the street, ringed by towers and named for the designer who died just weeks before it opened.

UniCredit Tower: The Tallest, With an Asterisk

A glass office tower topped by a soaring spire, the tallest building in Italy by total height, anchoring the north side of the square.

Bosco Verticale: A Forest You Can Weigh

Two residential towers whose balconies carry more than seven hundred real trees, a living facade that is also a genuine structural load.

Biblioteca degli Alberi: The Library of Trees

Biblioteca degli Alberi: The Library of Trees

A public park of about nine and a half hectares organized as a set of circular forests, each dedicated to a single tree species, laid out like a botanical library between the towers.

Grattacielo Pirelli: Milan Reached Up Before

A slender modernist tower from nineteen sixty, the Pirellone, that proves the new skyline is a sequel and not a clean break.

Stazione Centrale: Where the Land Began

A monumental nineteen thirty one railway station whose vanished rail yards became the very ground the new district was built on.

Best Time to Visit

Late afternoon into early evening is ideal. The low sun lights the glass towers and the trees of the Bosco Verticale, and the illuminated spire of the UniCredit Tower and the lit facade of Stazione Centrale come alive at dusk. Spring and autumn are most comfortable; the district is largely open and shadeless, so avoid the midday heat in high summer. The route works any day of the week, since every stop is a free public space or viewed from the street.

Pro Tips

  • •Start at Piazza Gae Aulenti, which sits directly on top of Milano Porta Garibaldi station, so arriving by train or metro drops you right at stop one.
  • •The Bosco Verticale is best photographed from across the street or from the edge of the Library of Trees park, where you can frame both towers and their greenery at once.
  • •None of the towers are enterable: the UniCredit Tower, Bosco Verticale, and Pirelli Tower are read from the street, so plan the walk as an outdoor architecture route, not a ticketed one.
  • •Take a slow loop through a couple of the circular forests in the Library of Trees rather than cutting straight across; the design only makes sense when you walk between the round groves.
  • •The leg from the Library of Trees to the Pirelli Tower is the longest stretch of the walk, so treat it as an intentional transect out of the new district and toward the older one.
  • •End inside Stazione Centrale by walking up onto the concourse under the steel vault; it is free to enter and the scale is best felt from below the arch.

Safety & Precautions

  • Piazza Gae Aulenti, the Central Station concourse, and the transit hubs can be crowded and are known spots for pickpockets, so keep bags zipped and phones secure, especially near the station.
  • The route mixes raised decks, stairs, ramps, and some uneven paving; watch your footing on the steps down from the raised square and wear comfortable, stable shoes.
  • Much of Porta Nuova is open and shadeless, so in summer carry water, seek shade in the Library of Trees, and avoid walking the exposed squares in the midday heat.
  • The towers are private residences and offices with no public access, so do not attempt to enter lobbies or balconies; view the Bosco Verticale, UniCredit Tower, and Pirelli Tower respectfully from the street.
