A seaside town has in its DNA the need for an immaterial and above all lyrical relationship with the outside world, with what lies beyond the marine horizon, and consequently to establish an exchange of knowledge. Merchandise has always been an inexhaustible source of knowledge, colours and flavours. One cannot think of a port city without a market. The market, by its very nature, is the appropriation of an urban space; it is the identity of a place with a different atmosphere from everyday life, re-establishing a hierarchical order between public and private space; it is a room defined by colours, scents and light filtered by taut curtains. The project for Piazza d’Armi seeks to restart from an identity lost over time, giving back to the citizens of Ancona a new place: a place of belonging capable of accommodating all the needs of the city, creating a synergic and socially active place, capable of mending the city.
