Cultural quadrangle is a project in action in the municipalities of Barcelos, Braga, Guimarães and Famalicão. It was created to enhance the differentiation of these urban territories by promoting the networking between their main institutions and cultural facilities.The Quadrilátero's Magazine concerns this project and focus on 3 categories: culture, science and technology, art and history. Visually it was inspired by the square's basic shape, resulting in a combination between the rigid structure of the grid and a dynamic layout.
