Walls of the Sun and the Moon

The Wall of the Sun and Wall of the Moon are a pair of murals made of ceramics and designed by the Catalan artist Joan Miró for the UNESCO building in Paris. The works were carried out by the ceramicist Josep Llorens Artigas in 1955. Initially, the walls were installed on the Place de Fontenoy in Paris, but afterwards were enclosed in a building that was constructed in order to protect them from damage caused by acid rain.
