A wall of Tufo blocks running almost precisely North-South could maybe a foundation for a sidewalk. The blocks of 2264 do not go as deep as 2288, therefore probably two separate trenches were dug and they were laid separately. No construction cut was identified or documented. The material excavated between walls 2264 and 2287 (from SU 2287) was rather early. (roughly archaic)
Two walls - 2288-east, 2264-west
