"""What are you taking along with you?"", this is what one of the first pages of the St'ART Book asks. The St'ART Book is the logbook that students and teachers have filled in for each mobility of the Erasmus St'ART project. Someone answers ""fear"", someone ""hope"", or ""desire to meet people"", ""desire to escape”, someone else freedom, knowledge, curiosity. ""And what do you bring home from this experience?"" is what the final page of the notebook asks instead: the answers - both from students and teachers - are enthusiastic, they speak of energy, vitality, courage, greater self-confidence: ""I come home, but I feel changed "", says Alice, ""I feel richer after this week"" writes Barbara (a teacher), ""I want to travel again, meet new people, visit new countries"" is what most of the Icelandic, Italian, Spanish and Portuguese students write.The project, carried out between 2018 and 2020, called four European cities - Pistoia, Reykjavìk, Porto and Bilbao - and their artistic high schools, to discuss the theme of art with regard to the city, in the belief that art is a means of social change, it constitutes a common good. In writing the project, we were guided by the ""Bilbao case"", the city that was literally reborn after an appalling crisis, thanks also to contemporary art and architecture. We therefore immersed ourselves in the stories, traditions, visions of our cities, highlighting peculiarities that inspired proposals for the cities themselves. The starting point for all of us was the survey titled: ""If I say city, what comes to your mind?"".In Bilbao we made a site specific intervention, inspired by female figures of local folklore, in Reykjavìk the nature that dominates the city has taken over: videos have been created that mix together sounds, photographs, paintings also inspired by the sagas of the territory. In the heart of Porto, the industrial district of Ilhas do Bonfim challenged us to propose new visual solutions, housing utopias, that resulted from photomontages and assemblages. Pistoia was supposed to be the conclusion of the project with an exhibition, a performance, a conference with politicians and contemporary art experts and, when the pandemic prevented us from carrying out this phase, we decided to transform the entire experience into the website, www.erasmustart.com, where we talked about our two years of work, CLIL lessons, discussions among teachers, exchanges among students, relationships among schools, languages, latitudes, different training and education.The main results of this project were:•The arrangement of a contest for choosing a Project logo among students of the partnership,•The design of gadgets promoting the project,•The creation of Power Points, PDFs, videos, stop-motions, pictures, designs, posters, architectural designs and models.•The provision of school corners dedicated to Erasmus plus: on the website of the schools as well as physically in some areas of the partnership schools.•The creation of an online Twin Space dedicated to the project.•The creation of CLIL lesson plans for the project as a resource for teachers and students.•The ad hoc publication of St’Art book: the book was used by the participants during their mobility as a logbook. It was also useful in the phases of monitoring and assessment of the project.•The creation of a Website, a Facebook page and an Instagram portfolio.The back cover of our St'ART Book shows Erasmus of Rotterdam in the engraving by Albrecht Dürer, 1526; from Erasmus we tried to learn and keep the spirit, in the belief that every project in his name must be aimed at the growth of people free from prejudices. St'ART, which brings along ideas of dynamism, enthusiasm and, of course, art, is based on the idea that culture and comparison can produce an open, peaceful, borderless and fearless world.Partner CountriesItaly, Spain, Portugal, Iceland"
