Can Rigal is a public access park which connects the Barcelona and L’Hospitalet de Llobregat municipalities. Its central passage has, on one side, a Mediterranean pine- and oak-tree wood that enhances the Collserola landscape, and, on the other, a meadow area with a system of geometric platforms and plantations of deciduous trees where the area’s services and a children’s-game park can be found. The central passage is divided up into geometric bushy and grassy rest areas and parterres, which separate the two areas mentioned above. Its chosen flowers, which are always native, provide an alternating shade of colour shade along the passage and over the year. The most notable and unique elements of the park are its pergolas and porticoes with solar and colourful panels along the central passage that filter the light, create shaded areas and power the park’s electrical lighting. The landscape is a huge mat of gentle slopes which end up at the Besós side; they lead to adapted routes, and respect the visual transparency criterion. Can Rigal park meets environmental and sustainability criteria such as lighting regulations, solar-panel energy generation, use of recycled materials and, in particular, anything relating to vegetation and use of water.
