the main axes of the museum grid that is offset by 22.5 degrees begins with the arrival plaza, carries through the edge of the stairs up to the main entrance, aligns with the columns supporting the rotunda as well as the center point of the rotunda, aligns with travertine benches in the courtyard between the pavilions, includes a narrow walkway between the west and south pavilions, a staircase down to the cactus garden and ends in the garden. the corresponding cross axis starts with the center point of the circle forming the gri library garden, then passing to the center of the entrance rotunda, and aligning with the south wall of the rotunda building. although all of the museum is aligned on these alternative axes, portions of the exhibitions pavilion and the east pavilion are aligned on the true north-south axis as a reminder that both grids are present in the campus.
