Nature and artifice, continuing and completing a rehabilitation, anticipating and making a transformation – a simple magic – three new walls will dialogue with the old ones, the new ones tell their own character, a car park’s ground plays with the colours of green, irony… between the new library and the former barracks a wall of continuous words, love poetries… towards the city and the palace, a green and magic wall – a flow of colour will unify a context lacking in human quality.
