Parco Biblioteca degli Alberi (commonly known as BAM – Biblioteca degli Alberi Milano) is a public urban park located in the Porta Nuova district of Milan, Italy, between Piazza Gae Aulenti, Via Melchiorre Gioia, Via Gaetano de Castillia and Via Filippo Sassetti, on the border with the Isola neighbourhood. With a surface area of 95,000 m², it is the third-largest green space in central Milan, after Parco Sempione and the Giardini Pubblici Indro Montanelli.
History The park was developed as part of the broader urban regeneration project that transformed Milan's Porta Nuova district. In 2004, an international landscape design competition — "Giardini di Porta Nuova – area Garibaldi Repubblica" — was won by the Dutch studio Inside Outside, founded by designer Petra Blaisse. Dutch garden designer Piet Oudolf, known for his naturalistic planting style, also collaborated on the project. The total construction cost was approximately €14 million. The park was officially inaugurated on 27 October 2018 and remains open to the public around the clock.
Description The park takes its name from the concept of a library: just as books are organised by subject, the plants are arranged by species into distinct thematic areas. The park is unfenced, allowing it to integrate seamlessly with the surrounding urban environment. The park contains over 100 plant species, more than 500 trees arranged in 22 circular groves, and approximately 135,000 plants in total. Other features include a small pond with fish and aquatic plants, a hedge maze, a seasonal fountain active from May to September, picnic areas, a children's playground, a fitness area, a relaxation area with wooden chaise longues, and poetic inscriptions along the pathways.
Management and cultural programme The park is managed by the Fondazione Riccardo Catella, which oversees both its maintenance and its cultural programming. Under the name BAM – Biblioteca degli Alberi Milano, the park hosts a year-round programme of free public events, including concerts, markets, sports activities, children's workshops and initiatives linked to the Sustainable Development Goals of the United Nations.
