Four-Sided Pyramid, Modern conceptual sculpture at National Gallery of Art Sculpture Garden, United States
The Four-Sided Pyramid is a concrete structure in the National Gallery of Art Sculpture Garden made up of blocks arranged in a four-sided formation. The arrangement creates a clear geometric form that rises progressively from base to summit.
The work originated as a conceptual design in the 1960s and was physically realized in the late 1990s. The built version brought a decades-old artistic vision into physical reality.
The structure represents minimalist concepts through mathematical precision and systematic arrangements, reflecting architectural principles from different periods.
The work stands permanently in the Sculpture Garden and remains free to visit throughout the year. The garden offers open walkways for exploring the artworks at your own pace.
Each concrete block follows specific mathematical principles that create a balanced progression from base to summit. This systematic approach makes the structure a visible expression of calculated design.
