This large and degraded tufa ashlar block at the central-southern border of room G-1 is likely the pier for a now absent column. The series of reused ashlar blocks lining the southern limit of G-1 along the road, and another set of the ashlars in front of the Area F building to the West indicate the possible presence of colonnade or portico delimiting the road from the adjacent spaces to the north. We believe that this is part of a later phase of construction and that this is not the ashlar block’s original deposition. The primary reason is the block’s placement at a high level directly on top of the concrete layer of SU 6176. SU 6176, the tufa block SU 6175, and the concrete layer SU 6162 appear to form a base for the pier composed of this tufa block, SU 6127, and the tufa block to the East, SU 6128. The relationship of the pier to G-1’s earlier abutting surface levels SU 6161and SU 6178, and the height of this tufa block, SU 6127, close to the level of the imperial road also indicate a later deposition.
