Fluted tufo column drum and base that may have been part of an earlier phase. The column drum has a hole in the top that likely would have been used to fit another drum on top. The column sits next to where the road would have passed but is now surrounded by later walls, including 5866 and 5413. There are other possibly related tufo blocks that continue down the road.
Semi-circular wall south of column 5865 and Tufo column drum and base at southern limit of 5413. and Tufo ashlars south of wall 5387
