The role of architect in city-making has been the theme of unsolved debates in urbanism. Committed as performers and recipients of a holistic knowledge, architects-urbanists keep acting, still today, in-between idealism and pragmatism. The city, being frequently defined as a text, becomes the molten object where projects brought to materiality are able to build an intangible narrative. The paper presents the ongoing research 6by6, a compared analysis of cities where the apparent contradiction between idealism and practice is solved. Acknowledged American and European cities are analysed as a mean to illustrate the connections between the most extreme city-narrative – architectural manifestos ‒ with the most tangible material commitment – actual and implemented urban projects. This article announces them and reports on the manifestoes they are the cores of.
