The construction of skybridges has become more frequent in the last twenty years in high rise vertical cities. This structure represents not only an aerial connection model between high buildings but an actual urban infrastructure that is able to connect several buildings and areas of the city. Aerial bridges have an additional important role in the security egress programs of skyscrapers, allowing for the possibility of a horizontal egress procedure and for an alternative to vertical egress. This essay offers an examination of these structures, with the aim of understanding hoe they function, the architectural and urban potentialities they offer for the contemporary city and possible evolutions for the city of the future.

In Italy, building codes don’t require the presence of these specific spaces inside assembly buildings: only tourist and hotel accommodations are obliged to have them. In addition, neither specific information, nor prescriptions regarding their design are given (see Figures 1 and 2). This is an important consideration because it highlights the fact that designers and building tenants are probably not aware of the importance of areas of refuge. As a consequence, the occupants may not be familiar with their presence inside the building because they have never been trained or instructed to use them. Even in the case AR are present in a building, it could be difficult for people to notice them because these facilities have to be located in places that don’t interfere with evacuation routes and, consequently, they may not be immediately visible to people.

Evolution of large mammal populations in West Mediterranean Europe during Middle and Upper Pleistocene. A regional example: French and Italian Southern Alps.
Alpes-Maritimes (France) and Liguria (Italy) area contains numerous prehistoric sites dated from Upper and Middle Pleistocene. A biochronology of the sites is drawn after faunal associations and evolutionary stage of taxa: Terra Amata (MIS 11), Lazaret (MIS 6), Caverna delle Fate (MIS 5 and 4), Madonna dell’Arma (MIS 5), Arma delle Manie (MIS 4), Santa Lucia Superiore (MIS 4), San Francesco (MIS 3). It highlights regional features linked to geographical position of the sites: persistence of archaïc taxa during Upper Pleistocene (Hyaena prisca, Cuon priscus) and maintenance of large populations of temperate species during glacial periods (Cervus elaphus, Palaeoloxodon antiquus).
