All dwellings in Porto's city have a history with Bolhão, and the documentary ‘Back to the City’ (‘De volta à Cidade’) made by Building Pictures, is the story of the Bolhão Market told by the architects (that renewed the material and immaterial heritage of the building), the team of Nuno Valentim (Architecture & Building Rehabilitation), and the market traders. With these stories and images, the documentary portrays the impact architecture can have on improving people's lives.
