The proposed installation has a twofold value. On the one hand, the historical one: it will be possible to experience the natural and insidious connection between the church and the square as it was before the construction of the famous staircase. On the other hand, the playful one: the installation revives, in a modern key, those parades, games and events that took place in ancient Rome up to the 1800s (e.g. naumachie) and that could become unique attractions able to give a different image of those places considered sacred and untouchables.
