After the fall of the Roman Empire in 476 AD, cities moved away from open spaces. If before the barbaric attacks being next to a river would guarantee florid commercial exchanges, with the new historical conditions open spaces turned into an exposed easy target. Unaccessible natural areas became the most popular locations to guarantee the population’s security. Middle Age cities were indeed enclosed spaces surrounded by walls (or water in the case of Venice) and permanently guarded by soldiers. Through the cultural progress started in the Renaissance cities started their way out of the walls and slowly opening up to XX century Modernist urban design , were walls turned into archeological locations to visit.
The topic of the wall is back to our society (XXI century), even though people links through digital social networks that make the whole global population closer. Digital infrastructure is for us what rivers and streets were for Ancient Roman society: it enable connection for personal or business reasons and make people learn diversities of cultures, ideas, habits, lifestyles. Nonetheless the topic of the wall is trendy again. Besides the wall between the US and Mexico’s border, for which there are competition winners (believe it or not – I probably suggest to give a look at Manfredo Tafuri’s books, Antonio da Sangallo might be of help), wall is an urban and architectural “accessory” back to fashion on the topic of urban safety.
In north Italy a new residential suburban area in Treviso has been built within the perimeter of a wall to defend its community from crime. Interestingly enough Treviso is also the land where Palladio built his villas, which were one the first examples of unwalled architecture.
Recent events put attention on people’s security in public space. Nice, Berlin and London’s attacks targeted crowed spaces. The reaction to Berlin attack was to fortify pedestrian area accesses around Europe with concrete barriers. Historic and central areas became mini fortresses surrounded by police, in a similar style medieval castles were guarded by soldiers. Is this the answer? Do we need to fortify our spaces for safety reason? Do we want to go back of hundreds and hundreds of years? Walls belong to the past, together with fortified architecture and urban design (please keep Sangallo and his fellows to architectural historians not to designer). Walls don’t belong to our society and I don’t think that built infrastructure can give any answer to the problem we are currently facing. Besides the economic and unsustainable cost, people are smarter and dynamic. People adjust, while the wall, and any fortified solution, is there for ages with no possibility of change.
The approach I would go for is creative thinking. This article written by Patrick Dunleavy makes an interesting point around the way our security forces around the globe should focus; approach to security changes people’s behaviour, which is the one that can guarantee the safety of urban communities. A ban has limited impact; a way of thinking creatively, analyse data, patterns behaviour can lead to dynamic solutions with longer impact, which also adjust to changes. What I am proposing is a dynamic infrastructure of ideas that can be shared around communities and networks to learn solutions that adapt to local cultures. What I am thinking is an infrastructure of safety, that people from different cultures, background and with different expertises create to collaborate on making our neighbour, city or nation safer. As Dunleavy suggests, one of the 9/11 attacks didn’t reach its destinations; people reacted. I do hope we can prevent to put people in a danger that leads to sacrifice lives. The understanding of how we can create systems that make people prepared to react and act to save lives looks to me a solution that belongs to our time, our way of thinking and our social progress and innovation.
