After the temporary exhibition Noise, held at Cascina Terrarossa in 1997, Plensa conceived a permanent artwork for Celle to be built in the olive grove bordering the park. The structure, made of glass bricks, is divided into two identical rooms, each accessible by a door. The only differences between these tiny rooms are the writings inscribed on the glass wall that prevents any contact between them. On one side there are words with positive connotations (peace, young, rich, etc.), while the "negative" opposites (war, old, poor, etc.) are inscribed on the wall of the adjacent space. At night, the lighting fixtures on the rooms' ceilings impart a cold white light, making the structure appear like a house of ice in the middle of the Tuscan olive grove.
