This section includes three display cases:

• The first contains skulls and bones that show evidence of common Zapotec practices such as cranial deformation, trepanation, dental mutilation, and stone inlays.
• The second features an offering deposit composed of miniature pottery, greenstone beads, projectile points, and other artifacts.
• The third displays vessels from two significant valley-floor communities east of Monte Albán: Yagul and Mitla.
