Park of Can Solei Nature · Badalona, Barcelonès, Barcelona Historic park of Badalona with gardens and an old Modernist building, in the Casagemes neighbourhood, considered today the city's great green lung, both for its size and for its historical and landscape value and its plant and animal richness, within the network of metropolitan parks. It occupies 10.8 hectares divided between the former estates of Can Solei, already documented in 1565, and Can Arnús, which changed owners on numerous occasions over the centuries. Inside it there are the historic gardens, the former orchard area now unused, an upper esplanade used for public events, and a central promenade flanked by century-old plane trees that connects the two estates.
