This block was likely a part of some larger feature, presumably also of ashlar. It is somewhat out of alignment with Tufo block 7324, so these were probably not included in the same feature. 7325 could possibly be a column base or other structural feature, as prior to the construction of opus reticulatum wall 7375 it likely would have faced onto the piazza. This is reinforced by its worked nature. It is aligned with - and may have belonged to the same phase as - bases 7293, 7147, and 7145 to the north.
