William & Marys unique Commencement, which completes the symbolic circle begun by the opening convocation ceremony. Four years after they emerged from the Wren portico to the cheers of their classmates, the seniors now return in the opposite direction, passing back through the portico and into the Wren courtyard dressed in their full graduation regalia. From there, they continue their Senior Walk Across Campus to William & Mary Hall, where commencement ceremonies are held.
