Início > About us
Social impact, community innovation and public art in action.
Projeto Trinsheira transforms challenges into opportunities, communities into living ecosystems, and ideas into tangible projects. Here, each initiative has a purpose: to create a more sustainable, inclusive, and collaborative future.
We build a safe place
Projeto Trinsheira was born from the desire to transform social innovation into a concrete force for change and owes its name to the neighborhood basement where it originated, in the municipality of Espinho, and more specifically in the community of Bairro da Ponte de Anta. It began with a simple idea: to build bridges between people, communities, and territories to solve social, environmental, and cultural challenges. Meanwhile, through experimentation, collaboration, and an unwavering commitment to impact, we have accumulated more than 250 initiatives in 21 cities with partners from 17 European countries and the United States.
Over the past 24 years, Projeto Trinsheira has established itself as a living laboratory of co-creation and action, where young people, local organizations, and companies come together to design sustainable solutions for the future. From community activation to project incubation, including impact entrepreneurship, our journey has been marked by real stories of transformation, reaching more than 13,000 direct participants.
Today, we are a dynamic ecosystem where innovation happens at the intersection of people and real-world challenges. We remain focused on creating shared value and developing sustainable solutions for the national and international ecosystem, giving back to communities all the knowledge and experience we have acquired.

Trinsheira Space: Transforming Stories, inspiring the Community.
In the heart of the Ponte de Anta neighborhood in Espinho, an inactive space has been given new life. The once-forgotten B3 Store has been transformed into Trinsheira Space, a pulsating hub of social innovation and community creativity.
The restoration of Store B3 wasn’t just a construction project – it was a purposeful renovation. Every restored wall, every architectural detail respected, reflects a commitment to honoring the history of the neighborhood and of Projeto Trinsheira, while projecting a future of possibilities.
