BAM Biblioteca degli Alberi & Porta Nuova Skyscrapers, Milan

08/11/2026

BAM – Biblioteca degli Alberi Milano (“Library of Trees”) is a modern public park in the Porta Nuova district of Milan. It opened in October 2018 and covers about 10 hectares, which makes it the third largest green space in central Milan. The park was designed by the Dutch studio Inside Outside of Petra Blaisse, with plantings by the famous garden designer Piet Oudolf. Its name comes from an idea: like books in a library, the plants are grouped by species. All around the park rise the new glass towers of Porta Nuova, the most modern business district in Italy. Here you can see how green nature and high-rise architecture live side by side.

What to See

The park has more than 500 trees in 22 round groves, over 100 plant species and about 135,000 plants. Paths cross wide lawns and flower meadows, and you will find a small pond with fish, a hedge maze, a playground, a fitness area and wooden sun loungers. In summer a fountain plays, and many free concerts, markets and workshops take place. Right next to the park stands the Bosco Verticale (“Vertical Forest”) by architect Stefano Boeri: two residential towers covered with hundreds of trees and thousands of plants on their balconies. To the south is Piazza Gae Aulenti, a raised round square with fountains, shops and cafés. Above it rises the UniCredit Tower, which with its spire is 231 metres high and one of the tallest buildings in Italy. Nearby you can also see the Torre Diamante and the tall Palazzo Lombardia, the seat of the regional government.

How to Get There and Practical Information

The park is between Piazza Gae Aulenti, Via Melchiorre Gioia and the Isola district. The easiest way to get there is by metro: get off at Garibaldi FS (lines M2 and M5), Gioia (M2) or Isola (M5). Milano Porta Garibaldi train station is just a few minutes away on foot. The park has no fences, is open 24 hours a day and is free to enter. It is a nice place for a picnic or a rest during a city walk. The best photos of the skyscrapers are taken from the park lawns and in the evening, when the towers are lit up. You can combine your visit with a walk through the lively Isola district and Corso Como.
