This is an article on public art, city and urban governance. It is structured as historical narrative initiated in Barcelona in 1929 with the Mies van der Rohe Pavilion. It is both a written and a visual narrative story. For deliveries, with a hypertext structure. I recommend reading on screen and with a good search engine to link lecura and images with the expansion of information. It is not a history, is the summary of stories. Conceptual, cognitive and personal. We jump from city to city. Most of the images who join us have been taken by the author. Public art and urban design creates a mapping and a temporality in contrast with the literature on the topic, chosen personally and with an interdisciplinary vocation. The reader can follow the text or stopping at the tables. Combine text with pictures. Using the possibilities of augmented reality. The work concludes with a case study dedicated to Brancusi. Key Words: city; design; sculpture, public art, urban design, art history
