Located in the city of Lund in southern Sweden, this piece by Basque sculptor Eduardo Chillida is in the main square, in front of the city hall. Completed in 1972, it is known as Rymdfält av fred in Swedish, and was commissioned by the city council to represent peace.
When Chillida was in Lund in 1972 for the installation of the puzzle-like sculpture, which consists of six finely polished granite stones, he said that if there is ever peace on earth, only then can the outer block be moved out into the square.
A better idea of its construction can be seen in the stylized image used in a poster for a 1990 art exhibition in Lund:
