Mr. Pei’s addition to the National Gallery of Art in Washington, known as the East Building,
is made from massive blocks of Tennessee marble arranged around a triangular courtyard.
It was a rare example of a modernist structure that appeared so permanent and well crafted
that even lovers of traditional architecture were smitten.

I.M.Pei divided the trapezoidal site into two and design designed triangular buildings
joined by a central atrium.
In plan, section, and elevation, the interlocking volumes merge inseparably in a spatial dialogue
of rigorous geometry, technical innovation, and exacting craftsmanship.
Three flexible towers are organized around a light-filled central atrium,
providing space for exhibitions of different scales.
