Undoubtedly, the city we know today is chaotic, complex and unwelcoming, yet at the same time, it is loved and hated for those of us who live it. Despite all its disadvantages, humans prefer to live in the urban scene.

A metropolis causes mixed emotions. Some deal with our daily routes, with space we live in and we think belong to; some others, with collective memory, with the events sometimes traumatic and sometimes triumphant that have been engraved in certain places of our cities and in the minds of its inhabitants.

We present a series of researches that seek to know the passions that are loosed in a city, that understand human gatherings as emotional communities, with dynamics of complex identity and social cohesion, based on the effects and emotions as narrative and cultural constructs subject to time and space.

Cities have the memory of confined emotions that are complex, contradictory and, in most cases, ambiguous. We could try to ignore all these emotions, but they will helplessly define the physical and cultural structure of our cities beyond the whim of its designers and governors.
