BAM, the Library of Trees, is a botanical park in Milan’s Porta Nuova district, between Piazza Gae Aulenti and the Isola neighborhood. Its walking paths cross distinct landscaped areas, with plant labels that help you identify the greenery and a rose garden with pink blooms. Look across the park to Bosco Verticale and the surrounding modern buildings, or pause on the grass while children use the playground. BAM also hosts cultural activities, including yoga and poetry events, so check what is on if you want more than a walk.
A botanical park in Porta Nuova

BAM stands for Biblioteca degli Alberi, or Library of Trees. The park opened in 2018 in Porta Nuova, between Piazza Gae Aulenti and Isola. Landscape designer Petra Blaisse created a contemporary green space among the district’s modern buildings.
The name points to the park’s botanical character. More than a hundred kinds of flora grow here, and many plantings have labels. Follow the paths to see different combinations of trees, flowers, shrubs and herbs rather than treating the park as one continuous lawn. The landscaped sections have distinct characters, with a geometric layout that gives the space its structure.
Plants, paths and architecture

Walking is a good way to take in the changing sections. Stop to read the plant labels, and look for the rose garden, where pink roses have been noted in bloom. Seasonal flowers and aromatic plants add variety along the route; what is flowering depends on the time of year.
The park’s open green space sits in sharp visual contrast with the buildings around it. Bosco Verticale, the tree-covered residential towers, is a prominent sight from BAM. Piazza Gae Aulenti and other modern structures border the park, too. Take a pause on the grass or at a sitting area to look between the plantings and the skyline.
A place to pause and gather
BAM is used for walks, picnics and time outdoors with children. The playground has swings and climbing equipment, and there are areas for dogs. Along the paths, poetic phrases add small details to notice as you explore.
The park also has a cultural programme. Activities mentioned at BAM include yoga sessions and poetry events, as well as open-air concerts. Check the park’s website for current programming if an event would shape your visit. Entry to the park is free, and it is open around the clock, so you can fit a walk into a visit to the Porta Nuova area without planning around a closing time.
