Laura Roldão has designed the Leça River Green Corridor in Matosinhos, Portugal, recovering a heavily degraded environment where industrial areas, roads, agricultural fields and residential areas coexist.

The corridor has brought everyday life back to the area, becoming a space used by local residents for their daily routes, to disconnect, practise sports, walk or meet. The intervention thus recovers a previously degraded space as a place for social interaction and community activity.

For the Leça Green Corridor, Laura Roldão has proposed a pedestrian and cycling route, incorporating new footbridges that turn the river into a shortcut and improve connections between the different settlements and public transport.

Phytoremediation strategies have been used to improve the quality of the water and soil, while the riverbanks have been restored to prevent landslides. The intervention is complemented by native vegetation, contributing to the recovery of the river ecosystem.

Project description by Laura Roldão

The Leça River Green Corridor in Matosinhos extends 48 kilometres and recovers a very degraded environment consisting of a mixture of industries, main roads, cultivated fields, and residential zones. When cleaning up the area, the project treated water and soil with plants (phytoremediation) and rebuilt the riverbanks using local vegetation to prevent landslides during floods.

Mobility is another of the project’s key points. A four-metre-wide path has been built for pedestrians and cyclists and new footbridges have been added. The river has thus become a convenient shortcut connecting the zone’s villages with public transport.

Since its opening, the corridor has taken on new life. Many local people use it from Monday to Friday when going to or taking a break from work while, at weekends, it becomes a gathering place for sports, walking, and family picnics. It also hosts school activities, guided tours, and volunteer initiatives of planting trees and cleaning the river so that people can once enjoy what was once a completely rundown space.

Laura Roldão Costa (São Sebastião da Pedreira, Lisbon, Portugal, 13 September 1963) is a landscape architect, researcher and educator. She graduated in Landscape Architecture from the Instituto Superior de Agronomia at the Technical University of Lisbon in 1988 and received her PhD in Landscape Architecture from the Faculty of Sciences of the University of Porto in 2015.

In 2005, she founded her own practice in Porto, Laura Roldão Costa – Arquitectura Paisagista, where she develops projects in landscape architecture, urbanism and territorial planning, as well as project coordination and construction supervision. Her practice operates at different scales, with particular attention to biophysical conditions and ecosystem balance as determining factors in the design process, together with the social, cultural and economic factors that shape territories transformed by human activity.

Her work considers vegetation as one of the principal materials in the construction of landscape, addressing its evolution over time, adaptability, textures, volumes and chromatic variations. Plant selection prioritises native species, while also incorporating introduced species that form part of Portugal’s cultural and botanical landscape heritage. For Roldão Costa, landscape design does not end with the completion of construction, but continues through the development and maturation of the project, responding to ecological transformations and to the ways in which spaces are appropriated by their users.

Alongside her professional practice, she is active in teaching and research at the University of Trás-os-Montes and Alto Douro (UTAD), with a focus on landscape architecture, urban green spaces and the use of plant material. Her work has received several distinctions, including the Portuguese National Landscape Architecture Awards in 2011, 2012 and 2013, and the International Land Award – Nature and Artifice in 2022 for the Leça River Green Corridor.
