This seems to be a large base for some kind of pillar or column, and to belong to the same architectural design as base 7147. That the westernmost block of wall 7146 to the east was cut to accommodate this base - serving as a kind of foundation for it - suggests that the ashlar walls and bases are in phase with one another. The presence of these bases suggests some monumental facade or front for the rooms along the eastern side of the 'piazza'. Further exploration is necessary in future seasons to determine the full southward extent of these pillars, and generally the architecture of the eastern side of the piazza.
