One of the pioneers of Conceptual art, Sol LeWitt gave primacy to the originating idea of a work of art rather than to its execution. LeWitt had been developing these ideas in three-dimensional objects he called “structures.” Based on the unit of an open, rather than solid, cube, the works peel away what he perceived as the decorative skin on traditional sculpture, revealing their underlying skeleton, or structure.

Though he created structures in a range of scales and shapes — the permutations growing more intricate over the decades — LeWitt maintained the use of white cubes with a ratio of 1:8.5; that is, the open space between the edges of a cube is 8.5 times the width of each edge. Five Towers (1986), a later, more complex structure, rises more than seven feet high, culminating in four towers on each corner of a square, with a fifth tower in the center.
