Fill includes soil with frequent tile fragments, of all sizes, and stone. Were these tiles part of a drain lining or covering? This feature is the continuation of cut 20031 & fill 20032 from the Northern trench of Area 20000, cutting through Wall 20018, thus post-dating the Opus Reticulatum walls. This feature was most likely used for drainage as it mirrors simple drains used in farming today. SU 20102/20103 may be on the same alignment as similar drain found in 13000, 11000, and 15000.
